keep it running

[Doug]

my snowblower starts up very well but cycles up and down. it's almost like stepping on the gas and then letting up. I checked the carburetor and the gas line and all is in order. any ideas?

Hi Doug,

The surging is caused by dirt or debris in the carburetor. If it surges at idle it will be due to a blocked idle circuit in the carb. If it surges under load it will be due to a blockage in the transition circuit. The carburetor will need to be cleaned. It would be a good idea to also install a carburetor rebuild kit.

I hope this helps!
