Now this video shows a generalized procedure for adjusting the idle speed air/fuel mixture. They rub a little at full lock or just shy of it. I’m sure they rub pretty good when in a sharp turn and hitting a bump.But I just took it easy on the way home and they did fine, no rubbing. This video uses some general guidelines and specifications, but always refer to a service manual for specific adjustment baseline specifications. If you need help with carburetor tuning or need help understanding carb operation leave a comment below. There are several elements to any carburetor important in achieving this and these are the throttle slide and its cutaway angle, the throttle needle that is held into the throttle slide by a circlip, the slow or Pilot jets and then the main jet. The screw adjustment (explained in the video) is used to fine tune this adjustment at idle speed only. It has very little or no effect on off idle and larger throttle openings.


Studying it may help you diagnose a jetting problem not related to the idle mixture. All carburetors are basically the same but with some subtle design differences. They rubbed on my mud flaps only at about a 45 degree turn and at a certain angle. Below is a graphic that will help explain the different jetting effects related to the throttle slide opening and how each adjustable part in the carburetor affects the jetting at a given throttle opening. How much did they cost installed and all?

Great site by the way, I’m sure I’ll be hanging around more often. Re: 275/70R18 With No Leveling Kit I just put those same size and BFG’s on my truck last month. I had to wait on the leveling kit too. Whether your a professional mechanic or a novice this video will show you all you need to know to properly set the idle mixture. Even with leveling it, it still might rub slightly at full lock you might have to do some trimming.
