Have a craftsman 5.5 hp snowblower when it is in the garage running and you put the auger on you can see the govenor arm move some so that makes me think the govenor is working but you go and blow snow it wants to just kill the motor. This unit is only about 4 or 5 years old. If you blow snow in 1st gear and go super slow you can keep it going if you try in 2nd or higher it just kills the motor... any ideas what to check?? Thanks..

You need to take the bowl off the bottom ot the carb.
Run a wire through the center of the carb , this is the main jet , check the bolt that holds the bowl on see if it has any holes it it . If so clean them also.
Its not letting enough fuel in when under a load. GOOD LUCK.

Yes thanks for the reply. I have soaked and cleaned that carb a few times.. it just seems like it dose not speed up when you get a load on it. The rpms don't seem to pick up thanks..

Check your rpms.
Full trottle no load should be between 3000-3200
