The following are not my words but do describe perfectly what I am experiencing. I should mention that my car is original and I wish to keep it that way.
Thanks for your interest.
"I get some serious hesitation problems when trying to accelerate. Particularly after the engine is fully warmed up and the choke is completely off. If I depress the pedal too far in trying to accelerate quickly the engine stalls like it's gasping for air,
after a hesitation and some pumps of the pedal, the car will finally begin to speed up. This problem seems to also be engine speed related. A stomp of the throttle at a higher RPM will not result in a stall. "
