Well so far the plastic spacers are working. No boiling gas!! The carbs. are cool enough to touch with my hand. Before they were too hot to touch. Got a good synchronization on them now. I did the Carburetor set up and lean best adjustment. Got 1/4 turn out on the speed screw and 1 turn out on the mixture screw. I’m thinking the speed screw is not right. I’ve been setting the speed screw to 2000 rpm and turning the mixture screw in and out to indicate rich/lean for the idle circuit. Not real obvious. Seems like I’m to lean with 65 jets. I think tomorrow I’ll start over then use the LM2.
