Do you folks notice your power really dropping off in the cold/ snowy days? I feel like my truck (carberated) goes signifigantly slower up the hills in the winter. I know a little bit is reasonable, but this is really extreme. I've assumed it is my choke not doing it's thing right, but I wondered if that is just what these trucks do.

 

mine does it when its humid but its tore down so don't know about cold weather i have not looked into it yet as im rebuilding it...i have a weber and rv cam but it is tuned plugs look great and power is there 99 percent the time

 

how cold is it. it should run better in the cold because of denser air. if its getting really cold it may be so dense that your running lean. check your plugs and see what color they are. also check your mixture adjustment on your carb.

 

In such a situation I would wonder about spark leak. While running on a dark night look for a bit of spark jumping.
