About this part

The first cold morning of the season is when a snow blower's carburetor lets you down. This one fits the 8 to 10 HP Tecumseh HM80 through HM100 engines, which power snow throwers, generators, wood chippers and pressure washers.

It replaces Tecumseh 640260 in all its letter versions as well as 632689. Put it on in the fall and the first snowfall becomes a first-pull morning.
