I have a honda 216 self propelled mower which backfired stopped running and will not start have checked plug, oil level, fuel,has spark,checked valves for sticking. When turning the motor over it's blowing back through the air cleaner any help would be appreciated. steve.
Thank's Pete but no dint's in the rocker cover it's got me stumped. Took the head off lapped the valves the exhaust seat was a little worn but still no joy. Have thought about replacing the engine but not sure which model gxv160 has the pto drive. I have looked at buying a new mower but which one,not too keen on belt drives. Steve.
Sometimes the simplest of things can be overlooked. Usually checking/setting clearances after valving lapping is normal but we do get distracted and forget to check it.
Just the other day I reinstall two ignition coils on a twin cylinder upside down and the engine I was working no longer had any fire. I had to take break and go over what was done in my mind before it dawn on me what I had done.
