All,
I've got a Craftsman walk-behind mower with a Honda 5.5hp engine (model 917-388820). The engine is misfiring or backfiring. I can see flame out of the exhaust sometimes. The spark plug is dry fouled. I've cleaned it and re-gapped it to 0.030, per the manual. The RPM seem low and of course it doesn't run nearly as smooth as what I think it should.
I don't know anything about small engine repair, but with your assistance and/or a good manual I can fix this mower. Any suggestions would be most appreciated.
Keith
