Walbro WJ-67B Carburetor for Stihl 066, MS650, MS660 Chainsaws 1122 120 0621

Replacement carburetor from Walbro. These carburetors come stock on a great variety of outdoor power equipment, including professional chainsaws. Carburetors can be problematic with today's high ethanol content, and sometimes replacing the carburetor components with a carburetor kit will not fix the issue. A new carburetor will usually do the trick.
