    It is about 7 below zero today and went to start the k5. It ran fine for a few seconds then died. when I started it back up it ran real rough and was missing horrible and backfiring. I tried to let it run for a bit, but no help, it just kept dying. It did this a few weeks ago when it was below zero also. When it happened that time it turned out that the ends of the spark plugs had un screwed a few turns. the plugs are accel shorty plugs. the motor and ignition are all new within the last few years.
    What would make the ends of the spark plugs do this when its cold. it is far to cold to mess with it tonight so we'll see how it goes tomorrow.

    .honestly, get some delco plugs, and tighten em up. and perhapes spray some starting fluid on each of them when you put them in, and see it it wants to start and run. /forums/images/graemlins/thumb.gif.

    Could have been the temp change between day time and night time. The block could have expanded and then contracted very quickly. What was the day time temp that day? Here in Calgary we sometimes in the winter get the Chinook winds during the day raising temps to +10/15 C. then drop to -20/25 C. at night (sometimes a 35 degree drop). That screws lots of things up. Do you use a block heater or AF heater? That would really make a big difference for starting in the AM. IMO, the AF heaters work way better than block heaters.

    Ithink he meant the small end where plug wires go on.Had same prob with accel ugrooves.I caused slight stutter under load.I crimped the threads with cutter edge of pliers a little to make threads tighter.No probs since.Sounds like small amount of water in fuel if only happens when that cold. /forums/images/graemlins/thumb.gif
