Burning oil in Lawn mower.?




balls


So I just got a lawn mower on craigslist, and I fixed it and now it is running good. But the one problem is it is emitting blue smoke, which means it is burning oil.

It is about 100 degrees here, and I used 10W-30 instead of the recommended 30SAE motor oil when it is over 40 degrees outside. Do you think this may be the reason it is burning oil, and maybe not my rings? Also there was oil on the air filter from the breather tube, do you think the oil from that is going through the carburetor and then its burning that?



Answer
Big Guy is right. However, I would suggest you pour in an egg-cup full of SeaFoam into the cylinder via the spark plug hole and let it sit for 24 hours. This will un-stick a stuck ring and clean out the valve seats too when you eventually pull on the cord.

what happens if i put vegeteble oil in a lawn mower engine?







in the crankcase


Answer
you will destroy the engine. Veggie oil is not made to withstand the friction of a combustible engine and the pistons will first overheat, then expand, then crack the cylinder walls finally causing the engine to seize. Other than that, not much
