[QUOTE="Rich Rohrich, post: 1248274, member: 16241"] They come from the factory with very lean low speed jetting. Even on hot days it's lean, on a cold day it easily needs a full pilot step richer to be right. At the very least adjust the pilot fuel screw farther out to richen it up. Keep in mind not to take it past 2 1/2 turns from the closed position. Past that point there is very little spring preload on the screw and it can easily fall out from normal engine vibration.
