I have a 67' gas, with the Holley carb. When we were bringing it back to life, we pulled the carb and it was a mess of gunk inside. Cleaned up all right but the accelerator pump was stuck and finally removed, but the cylinder has some rough spots on the walls and the seals were "ok", but the pump is not even part of the rebuild kit. Anyway, the beast starts and runs like a champ - except for accelertion, where it just stumbles and bogs, until it reaches RPM, then it is fine. The foot accelerator pedal is not hooked up, but even nursing the dash lever, makes it stumble, until it gets to speed. Would an accelerator pump problem cause this, or should we be looking at time, govenor, or something else? Thanks
Accelerator pump shouldn't affect it much unless you snap open the throttle. Which holley is it? I don't get along well with holleys so i dont have a whole lot of experience with them, but a popped power valve can do weird things. Sent from my DROIDX using Tapatalk
Stumbles on Acceleration More than likely it is just not adjusted properly. To check if you have a good fuel to air mixture, try this simple test. Get access to the carb intake. Take a rag and put over the intake with the engine idling. Results 1) If it speeds up = to lean 2) If it slows down = to rich Adjust carb )) Paul The buggyman
