have a Lawnboy z310, the zero turn mower. Son was mowing and it 'just died' according to him. Can't get any details from him, anyway.
Thought it was a neutral safety issue. Check all the switches, ohm'd and checked all continuity on all circuits. All is good. Was going to check the spark plug and pulled off the wire, it broke the wire and the igniter, so got a new one and a new plug.
Crank it and get fire to the plug, next check for fuel, put new fuel filter in and new bottom carb solenoid, all work great.
find that it's pushing air back through the carb when try to crank it. Still don't get the motor to 'hit' or turn over any, NONE. Pulled spark plug, put a compression test on it, ZERO compression.
So I am guessing it could be a valve issue?
I am a fair car engine mechanic, should I pull the head and see? Is that the next best step?
