Trying to get my 56 road worthy. Seems to idle/run fine but stalls when accelerating under load. Almost seems like it is better when in reverse. I believe it is the stock 4bbl. Do most of you guys try to use these carbs or switch to something else? Worth rebuilding?? It was in storage for about 15 years. I have drained the gas, added fresh fuel with seafoam but that is it. Any advice would be appreciated.
