Well, a very lean condition can cause backfiring.

Before we have you tear the carb off, lets try a few things.

Is the little vent hole in your gas cap blocked?

Is there any fuel in your fuel filter?

Are your gas lines cracked?

Is the vacuum line to the fuel pump cracked?

gas is fresh I pulled the gas cap off took fuel filter off crank it over good fuel vol. pulled the plugs look fine. still runs like crap. poked around tap on some stuff start to clear up after 10 mins. let her cool down and washed it off . seems to be good to go. I'll check out the fuel line... I never thought of that.

thanks Daye
