Briggs RPM Runaway Problem on Snow Chick Original Message Jul 29, 2005 1:36 am
I have a Briggs Stratton carb issue that has me stumped...
I picked up (for free) a 1960's Snow Chick (a baby brother to the Yard-Man Snow Bird) mini 2 stage snowblower with a Briggs Stratton engine model 80302 (3 hp). I cleaned out the carb & got the engine running, but the RPMS went to the Stratosphere! The governor arm moves the throttle to the full opening position when the engine is off, and arm appears to move (to lower the throttle) as the RPMs increase, but this has no effect on the engine speed - it just revs up to a catastrophic level. I have everything hooked up properly ("S" link & spring). I wonder if I set the idle & high speed needles correctly - 1 turn on the idle, 1.5 turns on the high speed? When I move the throttle down manually, I get a good low speed level but the engine speed is erratic & the exhaust smells rich. The carb is not flooding. No vacuum leaks. Any ideas?
