what shlould my stock needle should be?? my valves are all outa wak but when i stab the throttle it dies but if i go slowly its fine ive got a 128 main and a 40 pilot

[dirtdawg]

go to a 130 or 132 and you should emliminate the stumble. the needle will not make that much of an impact because when you go slow it is fine, so the needle and stuff is fine. if you stab it and it stumbles, the main is too lean. if it pops on decel then the pilot is too small, but i think that is all set. fix the valves and bump up the main 1 or 2 sizes and report back to us.
