I sure its possible, it just might be more work than its worth.

I recently did a partial overhaul on my m103 this past winter. I took the intake, removed everything and took it to the machine shop for a "hot tank" bath. It came back to me in brand new condition. Im really glad I did it because now every time I stick my hand in the engine, i dont have to spend all day scrubbing grease off my hands.

Your throttle linkage is probably sticking too. You will be happy you did.
