Carbie problems

[pocketcrotchrocket]

Hey fellas, i have 2 problems with my carbie, not sure if they have been answered or not:

1. Fuel when my fuel swith has been left on a lile while, will leak fuel out of the air intake from my air bux (out of the inlet)

2. When i am accelerating, and i jump to full throttle, it bogs and almost dies

Sounds like a dirty needle and seat and its running very rich. This may help..

The "my bike wont start and/or leaks" thread

Any help on how i can clean/ lean it out?

Read the link i put up on how to clean the needle and seat

Ok guys, how do you tune the engine, i tried the screw with the spring on the side and that must be idle.

Problems are as follows:

1.Takeoff from stand still on full throttle creates bog and almost dies.
2.When idleing, if you rev it a little bit, revs increase, but when released, idle remains high for a few seconds and dies down.

you may have to re jet it to a smaller jet size
if your not already running a NGK brand plug id advise getting one a bad plug can also cause bad spark & not burn the air fuel mix

once you have done those 2 steps you could could try a 10 degree advance timing key it may help also

yea my plug is a black colour...

i also made me exhaust a straight through a while ago, still has expansion chamber and works fine.

Im running oit on 25:1, should i be using 50:1 or 30:1?
