stihl br430 br450 boggs how to inspect the bearings.

[@patrickdchow]

I got the same Blower, do you know how / what causes the engine to backfire?

[@smallengineguys]

timing? first pull recoil. check crank for movement. move crank up down right and left. if it moves you have bad bearings creating bad timing and lean fuel. if not you might have a bad plug or bad coil or the flywheel key is stripped
