I ran that model number through Briggs & Stratton. They say it doesn't exist.

B&S sometimes has a different part number than the equipment manufacturer. However, for the present issue, entering the model number 13AC762F into the search on mtd site indicates this unit has a Kohler engine. I think the OP should send a pic of the engine numbers so we can first figure out what is in the mower.

Of course, as mentioned previously, all the carbs work pretty much the same for small equipment. Given that the OP already used a wire and carb cleaner and verified spark and compression, I think the next step would be to just replace the carb. No guarantees but the fuel seems to be insufficient to start the engine.

Lawn tractor carbs have a fuel shutoff plunger around the bowl to keep them from backfiring when you turn off the key. Did you check that?

Now we're throwing Kohler into the mix. This thread started out with Briggs & Stratton and then I ran the Yard Machine model number and those search results indicated a Tecumseh. I don't think we will ever know for sure what this engine is. I agree that all carburetors function basically the same, but if you want to get the correct replacement carburetor, you most definitely need to at least have the correct engine model number; and in the case of Briggs & Stratton, you'll most definitely need the type number and sometimes the code number.

Ehhh....all you have to know is the manufacturer of your engine (B&S, Tecumseh,...) and then you have to know number stamped on your carburetor...

And then you xan go online and start to search... Like Tecumseh 632400a carburetor service kit (like on ebay or ratioparts or ereplacement parts or partswarehouse or similar)

Basically what I did. I took the numbers off the carb and matched to a replacement carb. They were identical in the pictures and the "replacement model"

Had good luck with carbs on eBay … very cheap for B&S mowers and my Chonda gens …

Put the new carb on that arrived in the mail. Fired right up. Cut a few strips of grass! I'm a happy camper.

Nonsense. It doesn't matter what brand the engine is. The same scientific principles apply to all carbs (and engines in general, big or small), and the same problems affect all of them. Power Mechanics Troubleshooting 101... You can't figure out why something doesn't work unless you understand how it works.


I bought a loaf of bread just for the wire. I'm going to give that a try and report back.


That could be a Seinfeld episode, funny. I only see plastic clips where I shop.
