Not familiar with this engine, so can’t help much with specifics….The carburetor might look simple, but I am assuming this is a 4 stroke engine… When was the last time the engine idled correctly for the owner? Did it sit after that with gas still in the carb? Was the carb dirty/fouled fuel when you pulled it apart the first time? Are you sure it isn’t losing spark at low speeds? You might want to put one of those inline neon spark testers between the plug and the coil wire and monitor it while trying to make the engine idle. All that being said, did you try a new spark plug?
