Cam replacement, motor poping out the intake
« on: April 22, 2017, 01:58:10 pm »
Hey, so i have a 19.5 single ohv thats poping/backfiring out the intake, already set the valves. Gonna try and replace the cam but can only find one from a 17.5! Will this work? And will there be any power loss! Thanks and motor is stock.

More than likely it is a carb issue. 

Make sure you don't have an intake leak.

Or a sheared flywheel key. That is, if one was used...
