I also check it both ways on the vacuum ported and ported when WOT & checked the centrifical weights and all is good.
Here is a pick of the alternator & distributor
is there a possible chance the who ever put the motor together didnt get the cam gear set right (didnt get the dot set at 12) maybe 1 tooth off. If so is there a easy way to chech that out without pulling the front cover off?

The red wire in the plug-in should be hot all the time, key on or key off. The one that looks black should be hot when the key is turned on, check fuses, it might even say choke on the fuse box.
You need to set the timing at least up to factory. You will have to idle the carburetor down and re-adjust it. If it's idling too fast when you check timing, the centrifical advance will be trying to come up, so it needs to be idling slow when you check it.
One tooth on the cam will be hard to check without pulling the timing cover but you can get kinda close.
If you know the valve timing event (exhaust close,intake open), you can turn the engine by hand, with drivers valve cover off, watch the #1 intake and exhaust valves. Turning the engine slowly to TDCE (top dead center exhaust not compression) you can watch the exhaust valve close and intake valve start to open.
The timing mark on the balancer will go past 0° and the valves should close and open close to cam specs. Valve opening and closing events are in crankshaft degrees. If you watch the mark on the balancer, the timing tab on the timing cover and rocker arm and valve movement, you can check cam timing pretty close. A tooth off will show up if the timing mark on the balancer is in the right place.
Holley carburetors will backfire cold cranking if the choke isn't working. Backfiring could have busted a power valve and causing your idle problems.
Check it out some more and post back.
