Thanks for the link to the msd web site run on issue. I will disconnect my fan shortly before I turn the engine off and see if it helps. But it doesn't always diesel now at the current setting that I posted previous.
No matter, the car is still running very rich. The B/G people won't go into trouble shooting from any aspect as they are sticking with the carb is too large approach.
Compression I don't think is a factor at 10.5:1.
Jets are pretty easy to come by so I will try it this weekend perhaps.
An earlier thread mentioned to crack the secondaries a little. I may try that to keep it idling and then turn in the mix screws
