Driving around today it looks like 35-50/- is the lean spot. Previous owner installed an LED meter on the dash that shows how rich it's running. Once I get below 18 vacuum, the meter starts to go up, so that tells me that the rods start to pull up then.

Also have to check the idle screws again, sounds a bit rich, but it could be the cam too.

On the upside though, its got some juice now! Which isn't bad since I move a lot of equipment and tractors.

akart again, The spring doesn't adjust the mixture,just when/how fast things happen. You are going to want to change the rods to adjust the mid range area which you have determined as being too lean. The jets will determine the fuel flow @WOT. I like the Eldelbrocks as I/you can tune it. Tuning info should come w/the kit or was it the carb, but if you have questions check the Eldelbrock site for the manual. Idle screw only adjusts the mix at idle.
