We are slowly making progress with the basket case Model M.
We still have an issue with it backfiring (popping) back through the carb and blowing oil out the breather. Valves are set correctly and it is timed correctly (I think). Timing light on #1 plug (closest to radiator) and I see DC in the timing window at idle. What would cause it to back fire?
New plug & wires. Distributor has an EI, so no point and condenser.
Sometimes it seems to run fine and then it starts backfiring again.
I have a video that I will try to upload of it running and backfiring.
