Thanks, Chuck.
Somehow, that 'used' passed by me, while I was looking the other way...[

Whenever I get an engine that is new to me, I at least test if it can hold peak without sagging.
About 15 minutes on the bench will no doubt help Wayne master this engine, through fiddling, trial and error, Etc, more than will fumbling with it on the model.
He is quite new to this.
Welcome to RCU, Wayne!
