This gasket set can be used on Walbro WA & WT carburetors. Most small 2cycle engines used this kind of carburetor. Carburetor problems is one of the major causes of 2cycle engines from not starting or running. The metering diaphragm dries out from lack of use, therefore losing it's flexibility to control the fuel. Gaskets also lose it's durabilities to seal between the chambers.
A good carburetor cleaning job, plus a new gasket set may make your 2cycle engine run like the day it was born.
