Yes, I could kill the engine by closing the idle mixture screws. I'm going to check the torque on the intake bolts next. I also notice that the vacuum is higher right after starting the engine from cold, getting around 14 in-Hg, but dropping to 9 when fully warmed up. I also get zero vacuum during cranking, supposed to get 4 - 5 at least. Thanks for the pyro tip. I won't have time to work on this until next week, Vintage races car show at Limerock tomorrow. And, I can compare notes with other guys there too.......
