You either have the spark plugs wires As$backwards or the primary coils wires As$wackbards !! Or, a bad power pak!

Re: Still Backfiring

hey cotester here's an idea to keep from all that cranking: I bought a 3/8" square/hex adapter so I could put a 3/4" socket on my cordless drill. Remove the pull start assy. and use the drill/socket setup to crank the flywheel. careful to let your drill cool down every few tries. a cordless impact would work great.
