I ordered this part for my 35 year old generator. Never expected to find it
It was an exact replacement.
When I need a part for any equipment (i.e. table saw, chop saw, lawn mower, generator, chain saw etc.) Replacement Parts.com is the first stop.
Thank you

I thought I would never find this air filter; a 35 year-old motor.
It fit perfect, and appears to work just fine. I bought a second one as a spare

It's an air filter, changing it is a no brainer!
This is for a Craftsman mulcher with an 8 hp briggs and straton engine. Others would not even show me a parts list on their site. I'm glad you're around.

I rebuilt the carb and had probs with continued float valve leakage. Disassembled and reassembled 4 times. Quit for the day. Then discovered a brand new complete carburetor ($34) cost less than the rebuild kit and parts. Ordered and installed easiky. All is good now. Learned a lesson.
