I have searched the entire engine for a number without luck. It is an Mtd/yardman self propelled 21" gas lawn mower with a 5 hp Tecumseh motor. Actually, I can see where the model number label was peeled off in the rear of the machine.

Ironically, there is a label with a number on the plastic shield, which is 4576CN, but this number pulls up nothing.

I am able to use the mower with a replacement carburetor but I would be miles ahead if only I knew the model #. Can someone look at my photos and enlighten me?
