OK, I got the carb off last night and pulled the jets out to verify the base combo I'm working with. As I was surprised with the rods being changed, so were the jets. I had .104 main jets, combining this with the rods, I found this combination on the Edelbrock calibration chart and this combo represente two steps lean on the cruise mode and three steps lean on the power mode!


Now, would that cause a lean off idle condition? I'm probably going to start from scratch at this point and begin as recommended above, new spark plugs and reset base timing (MP electronic ignition so no points)and set the carb at baseline, or possibly a step or two rich.
or is there a better place to start other than the baseline factory settings?
I'm still thinking I probably need to move up to the .043 acc pump nozzles from the .035s on there now




That's way too lean for a BB Mopar!!! Somebody might have been running that carb on a stock Chevy SB!!! Like I said before any carb needs to be properly setup for the motor/combo.

The stock 113/107 jets, 71/47 rods and .035 squirters on the 1407 Eddy 750 cfm carb is just about perfect for my mildly built 360. Probably alittle too rich as my MPG isn't great but I'll coorect that as time permits. I had too much pump shot and went to the middle hole plus bumped intial timing up 4 degrees. NO HESITATION on my carb. Sorry all you Holley guys!
