Left gas petcock open position all night causing a fuel flooded engine. Fired up but missing bad. Tried to drive the plugs clean but started blowing gas out of front cylinder exhaust pipe. Pulled back inside garage, removed and cleaned plugs. with plugs out front cylinder a little warm and rear cylinder hot, blew compressed air into spark plug holes and up both exhaust pipes. was at work so tried to drive home and engine started running very rough about half way home popping flames out exhaust. Replaced plugs and now it runs great again but smokes like crazy. Smoke is worst when engine rpm is dropping ( when let off throttle). Front cylinder cleared upa little today but rear cylinder is still smoking very heavy.
Valve guides?
Valve guide seals?
Clogged return somewhere?
Breather not working?
Head gasket open oil channel to cylinder?
Please help...
Thanks,
Greg
