Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've got a Yardman 644E, 8hp/24".  I ate a brick which stopped the auger, the shear bolts did not shear, two auger drive belts snapped.  I've replaced the belts, but had a difficult time starting the engine.  It ran for about ten minutes and the snow flew out of the shoot, so I'm thinking that part is repaired, but the engine putters to a stop after a few minutes.  It was running great prior to the brick.  I was hoping for a quick fix--gas line maybe?  So I changed the gas and checked the fuel line.  Looks okay to me.  But, the engine isn't doing well at all.  Timing?

Ahh yes.  If you tightened the screw on the bottom of the bowl on the carb you basically turned the gas off going to the engine.  The stock setting is to unscrew it 1.5 turns.  Sounds like you found a good spot though.  Best to adjust under load with the engine warmed up so engage the auger when messing with it and possibly fiddle with it a tad as you run it into a snow bank.  You should get it right in the middle between bogging down and almost stalling and bogging down and spewing black smoke out the exhaust.

Glad everything is working once again.
