well i'm working on it for a friend and got it running good. but it was running out the overflow tube. so i installed a new float needle assymbly. and it still has a constant drip. i've tried adjusting the float. the only way i can get it not to drip is when adjusted to where no fuel even comes in the bowl. it's very frustrating. im about ready to take it to a shop just to set the float, but i've had that float dead on to the book. and tried to adjust it slightly a little at a time till it stops dripping, and when it stops dripping no fuel to the bowl at all.....any advice would be greatly appreciated.
