[QUOTE="RageD, post: 211325, member: 4512"] [SIZE=14px] I think this is how it always goes, right? :) [/SIZE] [SIZE=14px] Sounds like the float is too high still if I'm not mistaken (from the fouling plugs and leaking fuel). Also, idle screw all the way in and no difference sounds like your pilot jet may be too large. Have you tried going down a size? I was having similar issues and a smaller pilot seemed to fix this. Is it still happy even after giving the throttle a small blip? [/SIZE] [B]EDIT:[/B] I'm assuming the leaking fuel is from the overflow hoses btw and not the float bowl or somewhere else. That would likely be another problem. [/QUOTE]
