Need help diagnosing my Buda 4B153 engine. Under acceleration it
keeps backfiring. I?ve replace all plugs, wires, cap, rotor, condenser,
and points the gap is set to 0.022. I checked the firing order and it?s
correct. I tidied adjusting the timing on the distributor which seemed
to help a little. I also rebuilt the carb with new neddle and seat it came
with instructions on how to rebuild it. I set the air mixture screw 2
turns out and the main jet 3 turns out.
