Briggs & Stratton 691668 Air Cleaner Knob Replaces 493903 692297 281051

Great replacement for missing air filter knob on a lesco leaf blower.

I bought a used cub cadet 1170 riding mower and drove it half a season not knowing the air cleaner has not properly sealed. The guy before me probably wondered where the extra wingnut belonged. I caught the absent nut when I decided to partly tear down the engine for a good cleaning under the cowling. I missed it the first time I looked at the filter but was thinking I might need parts for the governor and spotted 2 nuts in the parts diagram. The lower nut was for holding the filter secure and this nut is to hold the filter cover secure. The inner (lower) nut was being used where this one belongs. It means who knows how long this engine ran while sucking dust. No biggy. It's not burning through oil. It was the correct wing nut for the job.

Worked great on my snapper 28” with the 9hp Briggs.

All is good. Worked well right out of the package.

I have an older mower but this part was right on great fit to replace broken one. Great price too!

Works as expected from a OE Briggs part, I don't really know what else to write other then my lawn tractor is breathing clean air and this hekped make that possible.

Exactly the part I needed, delivered I’m B&G packaging. Worked perfectly.

Great product, fit perfectly.
