I need a little enlightenment on this Holley carb

Believe post #19.

My 1969 Dart 225 w/ Holley 1920 idled terribly for ~18 years liking to die at stoplights. This was thru 3 auto parts rebuilt carbs (even rebuilding some myself), fussing w/ intakes, head jobs. No mechanic could solve it, though I tried several head jobs they suggested. When a whole rebuilt long-block still didn't fix it, I tried a 4th carb and it finally ran like a dream. 1920's have a sealed metering block that can get clogged, and most rebuilders don't touch it. Don't believe that mechanics in the old days were more competent than today's.

Nobody mentioned that 1965- slants used a rotating shaft from the pedal. I think only the Carter BBS had linkage for that.
