Craftsman Snow Blower: Unsteady and erratic idle.

I bought a brand new Craftsman Snow Blower (Model: 247.889571. I used it for the first time today and after running it for about an hour, it developed an unsteady, erratic idle. It seemed to clear up after turning the choke to the half way position, but as soon as I turned the choke back to the run position, the idle became unsteady once again. Any suggestions?

Thank you for your question.

I am sorry that your snow thrower is having this problem.

This is not an uncommon situation with these new lean burn engines causing the engines to do what is referred to as hunting where the engine will go from normal richness of the fuel and then it will go lean and die down a little and then pick up again.

Most of these new engines do not have a fuel richness adjustment and so the carburetor will have to be replaced. It can also happen if it got some debris in the fuel that will slow down the fuel flow in the idle circuit.

When using the snow thrower and the throttle is wide open and it is working to blow snow it should not do that. It usually only happens at idle speed.

I know that when you have a lot of snow and you need to use the snow thrower I would suggest that if you plan to idle the engine that you turn the choke on a little bit to smooth out the engine until you can get a technician out to repair the carburetor.

This is more of an annoyance than a problem with the operation of the snow thrower.

I hope this will help.

Thank you for using Manage My Life.
