Holley Street Avenger
Hey all I have a Holley Street Avenger 570 CFM on a FE390 I upgraded to a 50cc accelerator pump, I had to replace the carb so I just bought another 570 cfm Street avenger & all I did was transfer the 50cc pump over & used the same accelerator cam but the pump lever on the new carb only moves about a third of the way thru the whole travel of the throttle, on the old carb it moved thru the whole transition, I can't for the life of me see anything obvious different,I also have about a 1/4 in of movement left on the pump at full throttle & the adjustment screw is all the way out,, Thanks for your thoughts
