I think getting a light on and checking the timing is a good plan! Also, and this is going waaaaaaaaay back to the Super Mod days (daze?) when we could only run 2 two barrel carbs, it took a bit of bending on the accelerator pump linkage rod to get the off-idle flat spot out of the little carbs..... Points should gap about .017 or 30 degrees of dwell if you have a tach/dwell meter. We also used to run really weak springs on the distributor advance weights. When you finally hit the right balance of timing, advance, and accelerator pump shot the carbs worked great!
