are you a good machanic

has anyone had this problem.? i just put together a small block 400 with alum heads and about 9.5 to 1 compression.with a isky 266 cam and anti pump up lifters. new edelblock 650 carb ,stock points type dist. and edelblock esp intake.the coil is a stock chevy luv 4cyl along with the rest of the eletrical.(the engine is in a 1972 chevy luc truck) heres whats happening it has ruff idel. so i pulled plug wires until i found that #1 is not fireing at idel speed. and the engine seems to miss at any RPM . but when i give it thottle it seems to rev up nicely. so a got out on the road and jumped on it and it went smooth and fast.so then i pulled over and pull the wire off #1 and tryed it again and it ran like hell. when i got back home i was ideling in driveway , its was ruff so i pulled #1 again on and off a few times and i cant tell the diff. so it is not fireing at idel. then i took the value cover off and made sure the lash was right i even set it loose a little. then i took a compression check and had a good 150lbs. still ruff idel no power in #1 so then i try changeing the spark plug wires with other cyl that was strong and that didnt work. tryed a new spark plug. no luck.. i noticed when i took the plug out each time it was wet. so i tryed playing with carb idel mixture thinking it was to rich so i leaned it out and still didnt pick up that cyl. i am going nuts here could a good machinic please help me with some suggestions thanks eric

Wet with what? Gas, oil or coolant?

I would put in a coil that puts out a little more voltage than the Chevy Luv one that is in there now. It's possible that at idle the coil isn't sending out a good enough signal. Check the alternator output at idle vs. when it comes off idle.

First you need to put a ballast resistor in line with a coil for a V-8 application. The resistor gives you the nessacery time consonant needed for the coil to reach full charge. Ask your parts man for one that fits any mid-60's chevy. Also did you hook-up your ground straps?. You would get better performance if you put in an HEI dist. with MSD heli-core wires. Thats what I run. You can check your plug wires with an ohm meter they should have 1Kohm/ft. That lil pick-up ote to be a blast to drive. good luck man.
