75 F250 Starting Problem

I'm having a hell of a time getting my truck to start when it's cold. I have power, fuel and air, but it just won't start without the aid of a spray of quick start. Once it's running and up to temp, no problem, but after sitting for a couple of hours, I have to grab the quick start again. I have even tried plugging in the block heater at night, but get the same results. It'll turn over but won't fire. I think I have it down to either poor spark plugs, bad coil or worn out points.

Any help or thoughts would be greatly appreciated.

Adjust your choke.

FMC400 has a great write-up...

You sure you have points? in a '75 you should have electronic ignition, not points.

Probably didn't even look under the distributor cap to know...

Yes it has points. It's a supercab, camper special, and I had the dist off a couple of days ago and cleaned all the contacts.

What about the choke? Does it work, is it adjusted?

What carb do you have?

The carb is a Holley 4160 (orig). It is possible that the metal spring in the choke is gone (again). I replaced it two years ago so it should be fine, but I'll check it this weekend.
