Last night I checked out a few basic items on my truck to see what was causing it to run so rough. Found out that the choke is stuck open, and the mixture screw was almost all of the way backed out. A good 1/2" or more of the screw was showing!! I adjusted it and the idle screw and now it runs much better. I think I still have a vacuum leak of some sort because when I cover the inlet on the carb over partially with my hand it revs up quite a bit. Am I right in my thinking? By the way drainsbe, the clicky for Roger's Website isn't working, it says that the address is invalid. What is the URL for that site? Thanks.
