A few weeks ago I recurved the distributor back to the stock springs and set mechanical adv to 24 degrees total. Based on this I set initial to 14 degrees. I also have vacuum can hooked to full port vacuum (below butterflies). Reset the idle down to 700-750 idle mixture on the Holley using vacuum gauge and took the car for a spin. Felt much better off of idle whereas before with the single, light spring I could feel the mechanical advance making the car act very strange right off of idle releasing clutch to get the car moving. Bring RPMs up to not stall car, release clutch, drop RPMs slightly, etc. and it was causing timing fluctuation which I could feel in how the power was being applied. That issue is now gone!

Up through 2500-3000 RPM the car felt better, but putting it under load, up hill, and giving it some throttle cause a loss of power and cough up through the carb. Felt like a lean condition to me, so yesterday I had some time to play with the car some, and jetted up from the stock 70s to 73s. I left the secondaries alone (80s). Took the car for a drive and it now has a clean/strong transition under load and the cough is gone.

I've checked the float level a few times, and understand that the general recommendation is that fuel should dripple very slightly out of the bottom of sight plug with a rock of the car. This isn't very scientific... I need to rock the Dart fairly hard to get fuel to slosh out. I can see the top of the fuel level inside bowls (front and back are set the same) when letting sit/idle.

I'm thinking the float level might be a hair low, but what is the general concensus here? I was thinking of possibly raising it some and going from a 73 back to 72 on primary jets.

Progress!

Thanks!
