Sorry the hear of the troubles but,

If the engine turns over and no smoke, you know it is getting fuel. I would suspect the blower drive. Pull the air horn and see if the blower is turning.

Hope this helps

Hi 5b Steve,
It sounds like the engine is starving for air. This is only a guess but maybe the air damper in the blower inlet got triped. The air damper is held open by a latch that can be triped by either the solonoid or by hand. The other possibility is the shaft that drives the blower broke.
Good luck, Sam MC8

When it cranks does it sound like it still has good compression? Did it get hot before it lost power?

Sits on the engine. Piston pushes crescent shaped arm that shuts off the fuel. If it doesn't relax you get no fuel. Last time it happened to me. I unbolted it from the manifold so the crescent arm could open and we could move...Cable

Here is the engine stop cylinder on top of the governor. If the piston is sticking out, it will keep the fuel shout off.  If you loose power to the solenoid that controls this piston or the solenoid fails, this piston will not retract. The piston can be moved by removing one of the 2 mounting screws and twisting the piston to the side so the piston no longer contacts the engine stop lever.  Jack

Interesting conclusion, but I thought he had said it would not start even with ether.  I would think that if there was ether, air and compression it would turn over.
