Black smoke and backfiring in stock 41 Ford
So my parents 41 woodie broke down yesterday. Its a new rebuilt engine with fenton duals and smitty glass packs. Of course there are a few holes in the smittys I patched to try and diagnose the problem while Im waiting for the new ones to come in. Shes still blowing black smoke and running rough. I checked the electrical, and all seems fine. Im leaning towards a clogged jet in the carb.
Any help would be appreciated. |

power valve bad--carb float set too high--inlet need valve has trash under it. clogged jets in carb would not flood out engine but just the opposite it would lean the engine out
