So as some of you know I just purchased a 51 B3C. My dad is an excellent Mechanic and we are having some trouble with this one.
We have replaced the following:
Plugs, Plug wires, Spark Plugs, Fuel pump and lines, Points, Condenser, Rebuild Carb., button and cap.
It is still on A 6volt System but we have been trying to start with a 12v battery (12v coil) and It almost starts
but never does. It pops and backfires a bit. We checked the timing and its okay. We plan on doing a compression
test as we think we may have a valve issue. Any ideas?
