Hi Norm, that looks like a Tecumseh carby.

I don't recall any Briggs engines using them. Are you sure it's not a Tecumseh 207?

To remove the bowl, carefully lever the wire clip off the bowl. The bowl may have stuck to the gasket. Watch out for a small spring on the end of the central tube when you remove it.

The float is housed in the bowl rather than under the main body.

Attached are some pictures of a carby I replaced on a 13HP Tecumseh. It was leaking fuel from the bowl gasket and made the engine almost impossible to start.

Hope this helps. Caleb
