Stupid Distributor Questions

Guys-
I replaced every piece of the ignition 2 times. Tried bigger jets, thinner step rods, timing all the way from 5º to 18º, set float level and drop, stiffer springs for the step rods, and the car still has the same problem.
I give up. If there is anyone local to CT that can spend some time here, I will pay you for your trouble including fuel costs & tolls if needed.
The freakin car has a misfire at light load. Full throttle blasts it will run like a champ, but it won't run smoothly in any other throttle position. It feels like there is one or more dead cylinders when it is doing it. Thats the best way I can describe it to ya's. Start from a dead stop, going up a slight hill, or accelerating from 25 to 35 MPH it will stumble/miss. Put your foot to the floor and it will leave 200' of rubber. I just melted about 1/8" of rubber off the tires in front of my house, and the car runs great! Get to a stop sign and drive off normally, it will run like crap.
Please PM me if you can come here and look at it. Like I said, I will pay for all expenses and your time.
