I bought an old Cub Cadet SR621 w/ an FJ180v as04 carb. Cheap. Seller's ad said it just needed a primer bulb. When I saw it he had the carb off. Looked like all the parts were there and the engine had (seemed like good) compression and no obvious major damage. After considerable negotiation I bought it. I cleaned the carb and put a new primer bulb and hose on. I got it to start but it wouldn't stay running. Took the carb back off and went through it thoroughly. Now it runs but surges up and down constantly. I know carbs a bit but I'm far from an expert and have heard that KAW/Walbro carbs can be tough to get right. I'm stuck. Still a carb issue... air leak or jet problem? Or maybe a governor issue?
