Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Hi, this is Russ, I'll be helping you with your problem today. THANKS! This is caused by trash in the carburetor. I would remove and disassemble the carb,soak it in carb cleaner overnight and rebuild with a carb kit from the local dealer. The engine is running very lean and the mechanical governor is trying to stabilize. A good soaking and carb kit is the answer here. Remember to DIAGRAM ALL LINKAGE AND PARTS SO REASSEMBLY GOES WELL.
