To correctly adjust the valves, you need to have the valve springs removed (L-head engines only) and the piston at 1/4″ past TDC on the compression stroke.

I got one that’s really stumping me
I just picked up a generator w/ 10 hp tecumseh hm100
I won’t start and wasn’t getting g gas
I latter found after cleaning the carb that it still wasn’t getting gas
It turns out it doesn’t have any compression
I pulled the head and found no matter where I was in the cycle the exhaust valve stayed open a little bit
I pulled off the breather and noticed that the exhaust valve has zero lash?
How can this be
