in all honesty these are not fuel injected computer controlled cars, and as such we should not expect them to be as smooth and troublefree as a modern car.
My carb ,I think is setup pretty close to ideal. I do however always change down gears and blip the throttle to clear the cylinders of the excess fuel that sloshed into the intake when I just hopped on the brakes, after accelerating so fast just a few seconds ago that I left huge black stripes on the road.......
You all know what I mean!!!!
