    Over the winter I thought I got my choke all tuned up. I got it so it started well in the cold, and if I had any more choke, it was over-choked and would run rough and crappy until the choke opened up. Now that it's warming up, the choke is not on at all when I start up, which isn't a big deal except that I also have no fast idle and the thing idles real low until it warms up. It seems like I need more choke. /forums/images/graemlins/confused.gif If I put the choke back, then I bet it'll be all messed up in the winter. Any suggestions? This truck used to live in Arizona and I remember having to kick down the fast idle after a few seconds even there, so I must have it messed up a little.

    Mine still lives in AZ. I have my choke set for 1500 rpm idle . I still sit for 3 or 4 minutes when I first start it , even though the choke isnt working in the evening heat this time of year. Perhaps you need to let it warm up a bit before you drive anyways, or just give it a bit more choke ( adjusting it with season change is easy - 3 screws and turn ) /forums/images/graemlins/k5.gif

    I wish I could help, but I find myself tweaking the choke eery spring and fall. I figure the real solution will end up being fuel injection.
