Customer Question

I have a Craftsman Mower with a Honda GXV 530 engine. It has been flooding and smoking black smoke.
I replaced air filter, and plugs. It ran better till it heated up. Then it flooded andfouled the new plugs and smoked so much that it stained the new air filter. I replaced the carburetor. It ran great till it heated up, then it began flooding again. Any suggestions?

Welcome to JUST ANSWER small engines, let me try to help you !! How old is the engine? Have the valves ever been checked? If valves are too tight, when engine heats up, they can leak and cause this. Valve lash, is .004 intake and .006 inch exhaust.
