Ok, Homer did something dumb. Du huh.

The exhaust valve lash adjustment was backed all the way out on one cylinder. The exhaust valves were not opening on one cylinder.

I know in reflection what happened. I used a big wrench to loosen all the lock nuts on the valve lash adjustments when I set the valves. I simply missed those two when I went through the valves. As the engine ran, the lash adjustment simply unthreaded.

That explains how the engine started out fine, but starting running poorly after 30 minutes.

I ran out of time and warmth last night so I didn't get to button it back up and try it.

Hopefully the snow will let up enough to today for me to finish.
