Lumpy:
Hello,
I am trying to get my 427 chevy dialed in for the season. It has a dual point mallory and a holley 750 on it. This winter I put on new plug wires, plugs, cap and rotor and new fuel pump. I got it running but it has a miss and won't idle. I pulled all the plugs and all of them look dark except cylinder number 1 which looks like it has never been run. I checked it for spark and it seems fine. The intake and exhaust valves are opening and closing fine. I re-adjusted all the valves just to make sure. I am going to change plugs tommorrow since the closest auto parts store is 30 miles away. Any ideas? Thanks....Lumpy Sounds like you covered everthing but the points in the mallory dual point distributor----when I ran a points setup, seems like I had to file them the first thing every summer to get the motor to start---if they are ok, check the voltage from the resistor(if you have one) some times too low a voltage makes a motor hard to start---
