Engine Hesitation

[Drache]

Talking to my cousin about this and he seems stumped.

My dart has a hesitation when stomping the gas pedal. Drive along and stomp the pedal to the floor the engine power drops for a split second then slams you back into the seat.

If you slowly press the pedal it doesn't do this.

Also if a manually downshift into 2nd and stomp the pedal, there is no hesitation.

I would say its a squirter problem, if you look down the throat of the carb and pump the throttle do you see any gas get pumped out? (primary side)

Type of carb? If its a holley dp, its easy to tune. Upping squirter nozzle sizes and accelerator pump cams will do the trick. If the engine is thirsty enough, you might have to step up to 50cc pumps.

I've had the same problem for years.  Unfortunately the Edelbrock Performer 'carbs don't allow a lot of fine-tuning...
