Good info. Thanks for the research. Unfortunately both of the .91hz I have had were used. And, no way to know what was run in them. But, all I’ve ever used was Curtis wildcat 30% which is all synthetic. I do run the .2mm shim.

This last gallon idle has been very good off of auto. So, I think tuning is good now—I did have to fiddle with the idle screw when I first got this motor.
if it ain't broke, break it.
