Stumble off idle
I have a fresh 59AB that has a stumble on acceleration, like off of stop sign. It idles well and if you give it more gas when it stumbles it runs well. The spot just off idle seems to be the problem.
The motor is brand new New Stromberg dual 97's on an Offy intake Isky 3/4 cam Bubba's dist. I am thinking it could be a jetting issue but maybe someone else might have a better idea. Thank you |

Re: Stumble off idle
Put the 97 accelerator pumps on the winter setting (the further out ball connection) and give that tight engine some time to break in.
