[QUOTE="4423mark, post: 175578, member: 2027"] my guess would be that the needle is stock just because the jets hadnt even been touched but i dont know for a fact. i think i set the float at 5mm what ever the manual said but i have a hard time trying to measure and set these really precise alot of times i will hook a hose to the inlet and hold the carb straight and level and blow through the hose and lift the float until i cant blow through it when the float is parallel with the carb body and it has always worked for me but maybe i am way off base. just did a top end with new rings and gaskets and the ring end gap was well within specs. i will say this that i went back out last night and turned the air screw all the way back in and brought it out about a 1/4 turn at a time until the idle was much higher than it was and that straightened it out quite a bit. but now i still have the 390 main in it i wonder if i should do a plug chop test or immediatley switch the main back to the 460 range. thanks mark you guys have been great trying to help me figure this out a+ guys [/QUOTE]
