This bike sat for an unknown length of time with gas left in it,
tried to start it....no luck. Drained carb bowl, and tank.
Put fresh gas in tank, and bowl would not fill back up. It sat overnite,
thought i'd try again in morning. It started right up , ran a little rough
but then gas started coming out overflow. took carb off super cleaned it, reassembled made sure needle was shutting off fuel. ran great .......
took it out today ....it ran super....idle kept raising a couple times....
went 8 miles or so and it strted leaking gas again out overflow tube,
if you plug that with finger, after 30 secs or so gas comes out the vent tubes.
still ran great the whole time.........is the needle tip bad? could the bowl overflow tube have a crack?
on the bottom of the carb is a brass screw with a t handle end...is that the mixture screw? how many turns out? i never changed the float level or drop.
I can ride it bud jeez a full tank lasts a half hour......

The screw you mention is the pilot (fuel) screw. Start at 1.5 turns out and tune from there.
