Is the cam already broken in on the reman? If not, you need to get it up to 2000 rpm quickly once it fires and run it for about 30 minutes. You sure you got the dizzy installed correctly on TDC of compression stroke of #1 cylinder?
Not just TDC of Compression stroke on #1,
But did he get the distributor rotor in pointing at #1,
Or did it slide around to the next cylinder in the firing order when the distributor seated?
The ONLY way to find out is to...
1. Locate #1 cylinder,
2. Remove Plug, and Locate COMPRESSION STROKE by manually putting your finger over the hole and detecting the piston coming up, (COMPRESSION STROKE).
If he used the balancer to find 'TDC', then there is a 50/50 chance he has the distributor in at TDC of exhaust stroke.
Once you have VERIFIED Compression Stroke On #1 Cylinder,
3. Use a Chop Stick, wooden dowel rod, soda straw to locate the top of the piston manually.
NO METAL IN THE PLUG HOLE!
Turn engine BY HAND until the piston reaches TDC, Top Dead Center, piston all the way at the top as near as you can tell...
4. Have a look at the 'Hash Mark' on the balancer.
See if it is at 'Zero' degrees or 'TDC' mark on the timing cover.
*IF* it is, then the balancer probably isn't lying.
*IF* it's NOT, then time for a new balancer! The outer ring has slipped on the hub and it's junk.
Now, if you...
VERIFIED COMPRESSION STROKE,
VERIFIED TDC MANUALLY,
VERIFIED THE BALANCER,
Then you can move to the distributor...
5. MARK THE LOCATION OF THE #1 Spark Plug Wire Terminal on the cap,
Mark that location on the distributor base housing,
So you know where #1 plug wire is when the cap is off.
6. Flip the cap, see if the rotor is pointing at the #1 mark you made on the distributor housing.
*IF* it's a few degrees off, usually FORWARD of the mark in the direction of rotation (Clockwise),
Then you dropped the distributor in one tooth too soon, you didn't back the rotor up enough before you dropped the distributor on the camshaft gear.
*IF* the rotor is 180 degrees or so out,
Meaning the rotor is more or less pointing away from the mark on the housing,
Then you had TDC of Exhaust Stroke when you dropped it on the camshaft gear.
*IF* the rotor is pointing at the mark you made, or slight before that mark, then the distributor is probably in the engine correctly and you have a different issue...
Bad Coil, Bad Module, No Proper Power Connections To The Distributor, Fuel Issues, Timing Chain Set Installed Incorrectly, ect.
