My 1967 Mercedes hesitates when I first press the pedal to accelerate, but the engine revives if I ease off the gas.
This is a regular gas engine and the car does run well except for this stall when
I first accelerate.
Check the accelerator pump action, it should squirt fuel everytime the throttle is moved, and I mean everytime, no little sputters or drips of fuel but a good spray.
