What causes backfires and low compression in an engine?
Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
