- Confirmed Fitment — Verified for use with the Multiquip GA-9.7 portable generator series and SGW-250SS welder.

- Genuine Multiquip OEM Part — Supplied as original equipment, ensuring material grade and geometry match what was installed at the point of manufacture.
The decompressor pin is a small but essential component within the engine's compression release system. Its role is to temporarily reduce cylinder compression during the starting phase, allowing the engine to reach firing speed without requiring excessive pull force on a recoil starter or strain on an electric start motor. When this pin is worn, damaged, or out of specification, the decompressor mechanism may fail to release properly — resulting in hard starting, increased starter wear, or an engine that will not turn over at all. Replacing a worn pin with the correct OEM specification part restores proper decompressor function and protects the surrounding engine components from unnecessary stress.
