fuel mix

im running astandard carb with a 130 main jet on a mollosi 210kit but cant get the fuel mix right when the tank is full its too rich (the plugs black and the scoots got no go)and when its on reserve its too lean(the plugs white and it goes like hell) theres any idears.

Very strange indeed. Maybe the fuel line in too long and you are starving for fuel when the tank gets low. Do you have a standard exhaust?

I would say that 130 is too big and that you have a fuel starving problem as well.


"You can adjust the float level on those too, so check that. "

Not on a standard carb you can’t, dylan-old-boy ;D
