Question i have a 1950 dodge coronet d-34 engine and it wasn't running but got it running i rebuilt starter changed gas tank , fuel pump, rebuilt storm berg carburetor and oil change. It has been running good for the past month or 2 and now this past days that I drove it it seems to back fire when I'm on the road I have to put stater fluid just to turn it on now didn't have to do that before. I don't know if that sisson electric choke has anything to do with it backfiring and not starting up. Need some advice????
