During take off she has plenty of fuel with no hesitation to top speed. If you mash the gas she doesnt accelerate or deccelerate but stay the same. If you hold her at a steady speed 60 she wants to surge, if you mash it from 60 again nothing happens. Fuel pump/filter or something else, points maybe. Help thanx Joe

Hi Joe, Welcome to TOC.

Sounds like a fuel problem. Try a fuel pump volume test, and check the fuel filter. If you are running a Q-Jet- its in the carb inlet.

Need more info first, however, to determine anything. What carb are you running? Is the engine otherwise in a good state of tune?
