Hello all new to the forum. I have a JD 757 mower with a 25hp kawasaki motor. I believe the motor is a FH721D The motor had went on this and I have rebuilt the motor but cant seem to figure out this issue of getting oil in the carb. When I rebuilt the engine I had to have the cylinder walls bored out. I put new pistons for the oversize bore with correct rings. All new gaskets throughout used the service manual that I got offline to guide me through. I did reuse the carb an air cleaner but replaced the gaskets and filters. I did some research and found suggestions saying that it could be the breather so I went ahead and replaced that as well. Still have the same issue. Any help would be greatly appreciated as I would love to have this mower back up and going.
