My Trail Boss starts right up when it is cold. After it has ran for a couple of minutes, it is extremely hard to start, and sometimes won't start at all, until it cools back down. Any ideas on what would cause this? It seemed to do better after I sprayed a lot of carburator cleaner in it. I have since cleaned the carburator from inside out and I am still having the same problem.

 

check the compression...you should have around 120#s
