I have a Craftsman Lawn tractor with a single cylinder CV15s

Customer Question

I have a Craftsman Lawn tractor with a single cylinder CV15s engine that won't start when hot. The starter and solenoid are new. The starter wil not spin the engine until the sparkplug is removed allowing the engine to turn over. It will then start. Any ideas?
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?
Customer: Do you have any better ideas?
JA: Do you plan on doing the work yourself?
Customer: Yes.
JA: Anything else we should know to help you best?
Customer: Does this engine have a compression release?

Hi my name is ***** ***** welcome to Just Answer. Yes the engine does but some kohler engines have hydraulic lifters so the valves can't be adjusted . Let me pull the service manual

I'm going to check on the valves etc
Customer: replied 24 days ago.
The engine runs sweet after starting. Could the lifters be the cause?
Expert:  Briggs-Fan replied 23 days ago.
it seems it can't get past the initial compression stroke . Reading your post does this only happen when it's hot ?
Expert:  Briggs-Fan replied 23 days ago.
You valves look to be adjustable , look on page 11.8 under reassembly
Expert:  Briggs-Fan replied 21 days ago.

Hi just seeing if you got the valves adjusted ?

Customer: replied 21 days ago.
I decided to say the hell with it. If I start it with a full tank of gas I can complete my work without stopping the engine. Ill worry about it in the spring.
