PB-580 variants and serial ranges can use revised components. Match A021004331 or WTA-35, the throttle connection, fuel ports, primer circuit, and mounting pattern.

Frequently Asked Questions
Q: Will this fit both tube-throttle and hip-throttle PB-580 models? A: The listed PB-580T and PB-580H applications are supported when the original carburetor matches.
