too many unknowns here. what does it mean the car doesn't run?

what is the initial timing set at? are you running an electronic distributor or points? is the distributor in 180 degrees? is there a thermostat in the car? if yes take it out. what carb is on the car now? take the throttle cable off the carb. I just ran across this on another site where the throttle cable was hanging up pulling the throttle blades open exposing the idle slots and making the mixture screws in effective. how many different problems are we fighting here. so lets take it one at a time.

also hopefully you didn't hone a full .003 out of the cylinders that's a ton. telescoping gages are not the way to measure the bores.
