I put a rope start CV493T Pro Command Kohler on a WB and this motor is very hard to start. I am running it in shop to get the rings to seat but was wondering if any one else has any experience with this kind of situation. I have had to use Sure Start in Carb to start. I have tried different plugs and different gaps. I took the carb off and took it apart and didn't see any debris or anything unusual. I am not sure if it is a valve or ring situation. I plan to take the unit in pretty soon since there is no way we can live with a hard starting unit in closed trailer.
