There also was a thread about adjusting the pump screw in order to relieve the hesitation. Anyone remember who posted it?

now about that needle, glue feathers on it and use it as a dart. they're terrible. the stock needle is for a choked off intake and exhaust, retarded ignition curve, and 85db's. it may look like an advertisement but there is a reason so many guys use the jd needles. it will cure the low end bog. you might have to play with clip position a couple of times to get it "perfect".
