Backfiring out carb and wont run right

Gonna toss this out there, distributor 180 degrees out. :blob:
It won't run 180* out.. it'll flame, cough and fart a whole bunch,, but it won't RUN..

Think about it.. 180* out means the valves on that cylinder are in overlap,, both open in most cases.. The piston has just come up pushing out the exhaust,, and the intake valve is just opening to take a charge of fuel... there is no compression..

hope it helps..
