carb problem...

[Paul400ex2002]

OK guys need your expert advice again....

When i snap my throttle open quickly from idle it sometimes bobble and if i hold it it stalls. It's jetted right, and everything, but i'm wondering if it could be because my needle isn't seating quite right?

anybody?

what mods you have? whats the temp outside? what jets you running?

Depending on your mods it sounds like it may not be a carb problem at all.
Check Valve clearance
Check Plug
Sounds like the cam may be out of time?? Same happened to me.

You need to fine tune your jetting more...;)

don't start goin into your motor because of a stumble on excelleration. I bet your jetting is off,,now whether it's on the bottom or top of the power I don't know...but i'm bettin your carb needs to be tuned just a little...

it's jetted perfect... i have a white bros silencer, no lid, and a uni filter. It has a 155 main in it and it ran awesome when i had it out last week. I rejetted it for 9000 feet and it ran perfect when i was up there, came back, rejetted for here, and it seems to stumble... I just put in a new plug, but didn't gap it, could that be the problem? What's the gap supposed to be?

well i fixed it... the throttle cable was a little loose, so i tightened it a bit and it fixed it. Dunno why that fixed it but it did.
