Paul, what a gorgeous site you have there!
Is that your augur, and did you try it? You might be surprised.
I have used Restore on a golf cart and It slowed the oil smoke out the tailpipe, you could try that as well.A few weeks ago I stuck some prestone ring sealer in my YM14 to see if I can slow down the oil burning. Using it today I think it has slowed it out the exhaust as it is nearly non existant there but I think the blowby is worse? I'll have to keep an eye on it. I did manage to seal up the injectors as they don't suck air or leak past any more but it still runs like a pig at idle.

Actually, is that in a yellow bottle? The stuff I bought was made in the US and to be honest I can't be sure it was Prestone?
