    Could be a broken reed valve, could be the ignition is out of time, could be rings not sealing. I just rebuilt one that had NO compression and it backfired when I tried to start it. Apparently the combustion gases were leaking past the rings and igniting the charge in the crankcase. Did a top overhaul and it runs OK now.
