Hi

I'm from NY and generally know a lot about engines. I have 4 riding mowers, all with B and S engines.

Here's my problem.
I have two vert shaft engines both have similar symptoms. L They do not idle very well, rough. Also they both smoke and spit a lot of oil up through the carberator into the breather. I can only keep them running by removing the breather which is oil soaked.
