    Remove the fuel line to the carb and hold it over a can and have someone crank it and see if it is pumping fuel.
    If it doesn't then the pump has gone south.
    If it is then change the filter. it is on the carb.

    Check for moisture in the distributor cap. That could be a very likely culprit.

    Gas line anti freeze.

    If you are having too much fun it's probably illegal.

    Pour a decent amount of gas into the carb, in the hole JUST in front of where the air cleaner stud goes. (q-jet) You're problem is that more than likely, the well plugs int eh carb leak, and after sitting for awhile, the float bowl is empty, as well as the fuel line from the tank. Adding fuel to the carb will let the engine run long enough to pull fuel from the tank, and get it into the carb. My truck runs fine if I start it every day, but if I let it sit for a week or so (car too as a matter of fact) I have to crank and crank for it to start. Or dump gas in it.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Alaska /Here from Ireland in Dec 2000
    Hi, I'm in Anchorage, moved here in 1998 from Ireland. My wife who is from Alaska, quickly informed me of the winter do's and don't regarding my K5, and successful cold weather starting.
    I installed a new heavy duty battery, I always use gasline 'HEET' NEVER EVER leave your gas tank with a low fuel level. Also, I plug my block heater in basically all winter. Temps here this last week or two have been dipping to 6 or 7 F at night, and way lower with the windchill. I also fitted a $50 remote start I got at Walmart.
    Now, a few weeks back, I had the no start problem, I removed the dist cap, took it inside, cleaned it good and dried it with a hairdryer, did the trick.

    So I should pour some gas where the choke is then? or the holes closer to the firewall?

    The "slot" just behind the primary venturis (choke blade) Its between the primaries and the stud for the air cleaner.
