What to Check Before Ordering?

If the chainsaw's serial number is not in the list above, only order if one of the listed numbers is shown in the parts catalog or on the old carburetor.

Compare:

Mounting hole arrangement
Throttle and choke linkage
Fuel inlet position
Fuel pump connection
Adjustment screw locations
WT-589 or WT-589A marking

After installation, check that the throttle fully opens and returns freely to the idle position. Before starting the chainsaw, make sure all fuel connections are secure.
