A B&S (at least the old ones) wouldn't lose oil that way, but if they did they would probably keep running for another year or two!
I am lucky that the B&S is so bad the oil level sensor doesn't work any more, so it doesn't cut out when the oil level drops.
I've had one of the estate workers out testing and now I am thinking maybe it is the rings. Nobody knows what the long term effects are, it seems to run fine, but did still blow a bit of visible smoke on start-up. Maybe that was just from all the crap I sprayed in to clean the head ?
When it was apart the bore looked in perfect condition but it did seem to have a lot of oil covering. I don't know how much to expect, I'd imagine a thin film, noticeable on your finger as a bit oily but not really noticeable until you touch it.
The bore looked like it had a lot more than 'a thin film' on it. I'd have said a 'liberal coating'. It was almost dripping, certainly would have slowly flowed down the vertical sides. Maybe that is what it is supposed to have ? Seems a bit weird though, seems a lot to me to be inside the chamber.
But - the plug looks good. Bit sooty but not like it is chucking oil up past the rings. The valve seats looked OK to me, bit of carbon but not clogged.
My logic says oil coming via the carby is misted by the carby and only enters on the suck stroke (when the intake valve is open) and gets burned before it can do much. Oil past the rings is blobs of oil and would enter on all strokes (maybe not the squash stroke but the other 3), and only gets burned on the bang stroke so fouls the plug and everything else much worse.
Buggered if I know though. I learnt everything I know about it from youtube.
Change your rings

Head gasket and oil problem... I think I have lost a lot of respect for you now.
I think you may need to do some more research.
It is a OHV motor, like so many mowers. The head bolts form a U pattern, they aren't a complete circle and the gasket tends to fail in the open bit of the U (not enough compression from the bolts to hold the gasket down presumably).
This then allows compression gases to enter the engine and pressurize the sump. The pressurized sump oil then exits through the breather, into the carb and gets burnt.
Hence no dripping oil, but uses oil. And as the 'failure' tends to happen when the engine heats up the oil gets burnt when the engine is warm and you don't get much / any smoke.
Mower used about 200ml of oil for every 5 litres of petrol. I figure this is too much.
But anyway, it is done, there were signs of gasket failure in the open part of the head bolt pattern, so I assume it is now fixed.
But I don't know for sure, it hasn't been proved in a court of law, so I will trial it by going to mow something and see if there is any oil on the dip-stick when I return (I mean the oil sensor stick thingy, not me)
So DYO research. Lots of videos on Utube about it. Its not up to me to tell you.
(I just realized, I didn't mention it is a Briggs and Stratton motor, hence, yes having no respect for me is actually very reasonable. I would not admitting to owning a Briggs to anyone in actual real life).
How did the world ever produce two people as useless as both Briggs and Stratton. You'd think Stratton would have punched Briggs for producing such **** or Briggs would have refused to work with Stratton if he is happy producing utter crap. Oh yeah, that's right they are Yanks. 'nuff said.
If your head gasket is blown the compression gasses escape through the gasket not though the piston rings into the sump.
Last night was the first time I was able to sleep on my left side, 9 days after my booster, due to the pain in my arm where I had the jab. I travel a lot for work and must have had every kind of shot that exists, multiple times. Never experienced anything like that before.

I had redness and swelling for two weeks, also never had anything like it before. Oddly, the trial doctors said it doesn't count because it was under two centimetres. Two centimetres is ****ing huge compared to zero.

I had Moderna a fortnight ago and had slightly worse reaction than any jab that I can remember. A spot of blood was left on the bandaid, but I thought that was just poor technique by the needler

Mine have all been Pfizer. First shot was a non event with zero reaction. Second shot had me feeling pretty crook for 24 hours, kind of what I expected. The booster was painless and reaction free for the first day, mildly crook the second day, with the arm pain and swelling starting on the second day.
Needle injection blood and pain are more or less random, aren't they? According to one of my kids, who is a registered nurse, you can be unlucky and hit a capillary and whether or not the needle goes in close to a nerve ending is also a lottery.

Yeah, but the head on these OHV motors has second chamber for the push rods to come up to the valves. The blown bit of gasket is between the cylinder and the push rod chamber, not from the cylinder to the outside.
So yeah, the gasket doesn't blow past the rings, but it blows into the sump via the push rods. The sump breather then goes to before the carby, so any gasses / oil has to go back past the needle in the carby to get burnt. This I assume means it is fairly well atomized and burns quite efficiently compared to if oil was sploshed up past the rings.
Maybe with the temp and pressure and the way oil burns it make no difference if it enters via the rings or via the fuel system ? I just assume via the fuel system would give less smoke for same amount of oil. Maybe not ?
Here, I pulled the old one out of the bin.
Yellow crosses are the head bolts, the other two holes are locating dowls. failure is between the round cylinder and the square push rod slot.
Happy to say my Briggs and Stratton has been running for 20 years on the original oil without running low. In contrast, I recently needed to top up the Camry which has only gone 6 years since the last oil change.

Absolutely no reaction whatsoever with two shots of Pfizer. Got a flu shot just before Christmas... Massive hard swollen red patch, the size of your hand. Same with the missus.
And the guys I know who had Moderna, they were mandated by their company to get the shots on a Friday in anticipation of side effects. Which turned out to be wow prescient, as they all spent the weekend at home sick. N=10.

My Moderna booster was similar. No pain on first day. Then pain kicked in on second day, arm hurt when I raised it above 10 oclock and I couldn't sleep on it for two or three days. Never experienced anything like that before.

From what I read of the court case (and saw when the live stream was working) the fault in this lies with the judge.
Seems like I am not the only one.
...leading Australian immigration law specialist Maria Jockel said......
Ms Jockel believes Judge Anthony Kelly took an "exceedingly narrow view" when making his decision to quash Djokovic's visa cancellation on Monday and did not take into account the circumstances surrounding the Serb's visa being granted nor his entry into the country. "I have not seen any definitive evidence that he actually got an exemption that met the Commonwealth requirements," she said.

www.bdo.com.au/en-au/our-people/maria-jockel
If Novak's visa gets cancelled today for several significant reasons and obvious breaches of whatever migration acts then the judge might look a little myopic in his judgement.
Again, I still think he poses no threat to spreading Covid into a state that has 30,000 daily case numbers already and that the requirement to be double vaxed to enter Australia from Europe might have been reasonable 18 months ago, but today it just seems pointless.
But that wasn't the issue the judge was supposed to be looking at.
And I still struggle to see how the judgement went "immediate release, no visa cancellation and no further case to answer", as opposed to a stay on the visa cancellation order, Novak to provide whatever the extra info he might have been able to provide if he had been given the extra 2 hours and a requirement for border dept. to review with this additional information. Hell, the judge could have also asked to see the border decision logic before it was finalized.
What additional information did the judge think Novak might have been able to reasonably provide if he had been given until 8.30 ?
Maybe we will find out.........

Hahaha, you are on the wrong side of history.
myscreenname has highlighted from previous statistics that you are 35 times more likely to be in ICU if unvaccinated.
Then yesterday it was reported from QLD you were 9 times more likely to end up in hospital if you were unvaccinated.

However when I look at the latest NSW Government statistics they seem to tell a different story.
Can somebody here who is good at maths please tell me based on the dashboard below;
1. How many more times your chances of ending up in a NSW hospital unvaccinated?
2 How many more times your chances of ending up in NSW ICU unvaccinated?

Given that there is 78.3% vaccinated and therefore 21.7% unvaccinated, your baseline for zero vaccine effectiveness would be that the ratio of people in ICU would be similar (ie. 78.3 to 21.7). However, since it is just about even for ICU admissions despite more people being vaccinated than not, that would mean you are around 78.3/21.7 more likely to end up in ICU if you are unvaccinated. That is, around 3 1/2 times more likely.
Or, for those that like decimal points, 78.3/21.7 x 49.1/50.3 = 3.52 more likely to be in ICU if unvaccinated.
For hospitalisation, it's 78.3/21.7 x 28.8/68.9 = 1.51 times more likely if unvaccinated.
That 93% omicron will be an interesting statistic to keep an eye on, although will self-reporting of RAT results instead of getting a PCR test impact the availability of this data?
It would be great to have the figures for individual age groups.

But he used the wrong input figures, did the wrong analysis and thus produced a nonsensical result.
Problem is it has been mentioned twice so is now the gospel truth.
If you want the actual number, you can't really get it.
35 times, 9 times, 3.5 times whatever, and you will immediately think that this applies to you. But it doesn't. You aren't average. Nobody is average.
Comparing general numbers of vaxed vs ICU is all well and good but it doesn't take into consideration many important factors. For example, how many people in ICU with covid are unvaxed because they are already so sick they can't be vaxed ? Should these people be included in the unvaxxed percentage when they are such a small part of the large set but such a large influence in the small set.
If you want a number that is anything but rubbish you need to compare how many people of your average age, wellness and general situation are vaxed / unvaxed and in / out of ICU.
And I doubt that any publically available data includes that level of personnel information.

...assuming that being vaccinated / unvaccinated is the ONLY factor in determining if somebody ends up in ICU.
If the unvaccinated are also 75% more likely to dance the night away in a mosh pit, then it changes the numbers.
The assumption that vaxed / unvaxed is the only relevant deciding factor is statistically unlikely. I'd say 95% unlikely.

This is a valid point. Everyone forgets that the vast majority of people who end up in hospital or die from COVID have multiple comorbidities.
These are the people that are at high risk and bump up the stats of any cohort they are counted in.
The only way to properly assess risk is to get the figures of otherwise healthy people who end up in ICU or death.
www.news.com.au/national/nsw-act/why-half-of-the-people-in-intensive-care-in-nsw-are-vaccinated/news-story/e935619886f9b4c4346b57e2d5744d1a
Around 70.2 per cent of the people who died between June 16 and December 25 last year also had not been vaccinated or received at least one effective dose (420 people).
This compares with 96 people who were fully vaccinated and 76 who were partially vaccinated.
Just statistics. Anyone is free to cherrypick what statistics they need to make them feel all warm fuzzy and safe.
They are even free not to take the vaccines.
I think this endless picking apart of the numbers by the unvaccinated just shows how scared they are of ending up in hospital.

Thanks for the doing the numbers Harrow!
Carantoc & Paradox I completely agree on all your points regarding interpreting the numbers when you need to consider comorobities, age, etc.
myscreenname, so can we agree based on NSW Government numbers that the overall risk for the unvaxxed to be admitted to ICU over the whole population as an average is 3.5 times rather than 35? It may be just numbers but 35 is 10 times more than 3.5 so it's worthy of rectification. Obviously these numbers are heavily skewed to the vulnerable in the real world. (I'm not even taking into account the 100,000+ of vaccinated who have had adverse reactions)
That article you referenced says "Prof Bennett said the ratio of vaccinated people in ICU would be the same as those in the general population: 93 per cent." The actual general population that have been vaxxed is 78.3% according to the Dashboard. Is Prof Bennett not being accurate or did I miss something?

According to wiki - "In epidemiology, the general population refers to all individuals without reference to any specific characteristic"
There is going to be a big strike in France by teachers today. Macron is pushing the vaccine pass through. It was a health pass and a negative test was OK. If it goes through you will have to be vaccinated to go to a restaurant,cafe,theatre and so on. You also will need it to travel on long distance trains and flights. They said they would never do this.
Yes all the numbers can be played by who is spitting them out to sound better or worse for their cause.
Heads of hospitals being interviewed on TV are saying unvaccinated count for 60-80% of COVID patients in France.
