Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I purchased a mid 1990s Toro self propel mower from a garage sale. My son and I really prefer these mowers over newer styles. I took it in to get "fixed" and the carburetor was unsalvageable. We dug around on the internet to try to find a replacement carburetor and couldn't find an exact match. Not being a mechanic, I'm not sure how precise we need to be in replacing the carburetor? It is a Toro model 20439 and serial id of 4903128. The part number we need to replace is 77-8050.

Stamped in to the valve cover will be some engine numbers post those.

Yep, just found those. The first is LMS23 and the second is 3143. These are stamped on the carburetor. Also, if it matters, WALBRO, was stamped in yet a different area. One more area that was a box on the front of the engine had these numbers stamped 97777, 0111 01, and 93120604

the engine was made for toro by briggs & stratton Briggs part number 497721 carburetor NLA but will give you more to google for

Thanks ajallen.

   The carb is a basic carb.  Why does it need to be replace versus cleaned or some
simple parts like float, needle valve & etc.?
