Shake Shake Shake

Sounds fine to me. I'd tolerate that shake. How are your mounts? They get swollen and squishy after being oil soaked for 55 years. Ever tune the carb? Give both screws a 1/4 turn one way and see if it changes anything. Can always turn them back.
Yeah I'm sure I'm stewing on it more than I should. The mounts are as new as the rebuild.... 20 years-ish. They could probably stand to be replaced. I've had a couple different carbs on there and same results. It's pretty dialed in. Thanks for the input!
