The exhaust header is loose on the head. Not sure the bolts might be stripped or sheared off. Gravity feed so no fuel pump to fix It did not have any oil but I think that happened when it was moved en mass with the rest of the engines. .
The good news is that it did fire with a shot of starting fluid.
The carb is off. I hit the outside of it with carb cleaner to wash away the old gas smell. It looked decent when the grime was washed away. Next I ran it in the ultrasonic with hot tap water a couple of times. Then I took the bowl and bowl o-ring off and ran it a few times in 140F water. Carb is 21473. Bowl gasket is stretched but I used it anyway wonder if it will leak. A new one is on the list of things to be ordered.
I wonder if this broken exhaust port is the only problem this engine has.
