Yesterday it purred. Today it pukes at partial throttle.

All better now?

Yep, purrs like a kitten again (while hacking up a fur ball when the engine is cold). How a 1" long strip of rubber got through the needle and seat is a mystery though.

Now I can go back to looking at how the manifold well - spring choke is supposed to work. I soaked the spring in white vinegar for a day and the spring and arm off the spring look to be free. It looks like the spring doesn't have enough tension to push the choke linkage closed. What looks a spring adjustment screw is frozen tight. Maybe I'll try to wind the spring around one more turn and see what fresh Hell that develops!
