just rebuilt runs bad

Will do, not sure what "timed port/direct port" means but I'll do a little research.

You guys may be on to something. I verified the MSD wiring several times but I did find that silicone inside the (used) MSD Dist.. I'm wondering now if it wasn't holding something that was put in backwards or covering wiring that was crossed.

Also, when I hooked up the Mopar distributor, I had to use alligator clips to connect to the MSD. It was dark and I can't say for sure they weren't reversed.

Going now to get the points Dist. this morning.

Thanks!

Direct port vacuum is on the base plate of the carb in most cases, if its a holley carb, the timed port will be on the left hand side of the metering block, but like mentioned, have it disconnected while setting the timing.

Oh while i'm thinking about it, if by chance you ran a jumper wire & disconnected the ballast resitor, you'll need to hook it back up.
