So, with the vac. gauge, adjust the mixtures until max vac.? I dont have anything other than the stock pointer on engine for timing. It goes to about 14 degrees. I usually run the highest timing just before detonation.

I have tried in the past to set timing with vac. gauge, but could not eliminate detonation at max vacuum.

Yep, I have had problems in the past with heat at idle. Had to get larger rad and more cfm fan. Maybe the full time advance will help that.
Thanks Denny
