I got the engine running on carb cleaner, but the belt stopped because the air pump was seized. I removed it & sprayed a BUNCH of penetrating oil into the 2 vent holes on the back, and into the intake & exhaust ports. After some propane torch action & a little hammering, it started turning again.

UPDATE: After several months & a few tanks of gas, it's still working fine.
