any info would be appreciated. thanks in advanced!
The "zipping sound" could be your slipper clutch, as the truck gains speed it's still under load and it can break the slipper pads loose making a "zippy sound".. Tighten it up and see if it goes away.
The truck dieing sounds like a lean condition. As you keep it floored it's burning up all the fuel in the crank case. If you rev it on and off the throttle you are purging it and it will rev higher because it's not wide open and still has fuel in it but it's still lean.
Sounds like you have 2 different problems. One is almost deff. a lean condition.
Factory carb settings are 4 out on the HSN and 1-1/2 out on the LSN or flush with the horn. You need a RICHER tune in cold weather.
