The bottom line: this unit is a straightforward, OEM-standard swap that fits a wide range of GX340\/390 applications and related generator engines, and its biggest selling point is compatibility with many part numbers. It is best for users who need an inexpensive, ready-to-install replacement rather than a heavy-duty, high-output starter.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Matches a long list of compatible part numbers so it will bolt in for many Honda GX340 and GX390 engines and popular clone replacements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated solenoid:\u003c\/strong\u003e The starter includes the solenoid in the housing for a simple one-piece swap and fewer wiring changes during installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM standard fit:\u003c\/strong\u003e Built to the OEM standard form factor used on generators and small engines, which reduces modification time and makes installation predictable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact power:\u003c\/strong\u003e The unit delivers about 450w of actual motor power suitable for typical electric start usage on small engines and portable generators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoxed with hardware:\u003c\/strong\u003e Ships as a single starter motor with solenoid in a box, ready for installation without extra packaging steps.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis starter motor is aimed at DIY mechanics, landscapers, and generator owners who have Honda GX340, GX390, or common clone engines and need a like-for-like replacement that covers many referenced part numbers such as 128000-2750 and 31210ZB80130.
