Easy Repair

The carb was an easy repair and installation, my snowblower fired right up no adjustments runs like brand new.

Great Part, work as expected

Arrived in good condition. Installation was easy. Cranked the snowblower up. Checked the low and high rpm's. They were set to factory specs. Solved the surging problem.
