You think it carries the wheel now, just wait :lol:

Really the QF is a hard carb to figure out but they seem to like a jet on the smaller side do you know whats in it now? Do you have a elec or belt fuel pump drive setup ?

84 Squared on a alky carb ? Are you sure, double check them with a drill bit and see because 84 is not at all right.

ok so .125's Yes it will eventually eat the seals up in the BG 400 so maybe buying a set to have with you at the track might be a good idea, they are on rj for 13.00 I think.

If its alky is right 6.0's maybe better if gas is off.

very common when switching alky will eat up the sub-par gas stuff for sure, I think eventually the seals will be gone in the pump, they are known for it.

Are there holes drilled just above the jets? Just wondering if it is a converted carb.
