i recently sprayed carbi cleaner into the top of the carburettor and where the fuel rises up threw them 2 little pipes with the sharp tops -
, the carbi cleaner came out all out of the sides of the resivior,,,,,running a hitachi stock carburettor

so it might have big vaccuum leak instead of just a little hole.

my idle is very rough- lets say if my idle was 850rpm it will jump to 900rpm, 950rpm,900,850,880,950,850
