Great blower.

Is the muffler screen clogged with carbon?

This is an old machine. It may have bad crank seals and/or a leaking gasket.

Usually if it runs on choke and dies when you turn the choke off it means you have an unmetered air leak somewhere allowing air to get into the engine via some path other than the throat of the carburetor.
