    I have noticed hat now that it is getting cooler, my K5 idles really rough when I start it. As should as it warms up it runs and idles fine. Any ideas to the problem. The carb has been rebuilt recently.

    Mine is doing the same thing. I did replace the plugs recently and I think they are the problems I bought some cheapo brand. My blazer does burn some oil and I think I may need hotter plugs.
