[QUOTE="oexing, post: 171654, member: 1493"] A partially blocked pilot jet and metered down idle air mixture would be same effect like a very small pilot jet. You´d notice that condition at once as kickstarting the thing will be a pig. The idle mixture would be reduced so the engine will not want to run at idle speed. Basically with correct idle jetting the picking up from idle is the job for the slide cutout. After that stage the needle jet and needle come into the business at say quarter open, typically at town and overland speed. Here the reported engine stumble from too rich part throttle can be noticed. That is why I believe the root of the problem may be. The float chamber and float have been checked already ? Vic [/QUOTE]
