#155164 IowaRoadie (User) In youth you learn.... In age you understand Senior Boarder Posts: 340 Is my carb supposed to look like this?? 3 Years, 4 Months ago   Checking the jetting and when I pulled of the air cleaner assembly, I noticed the black sliding thing in the center is over half way closed. What does this piece do, and is it supposed to be like that?   Logged       The administrator has disabled public write access. #155169 S7driver (User) Fresh Boarder Posts: 42 Re:Is my carb supposed to look like this?? 3 Years, 4 Months ago   Mine has one to. I think it is part of the Constant velocity setup. I sure somebody will clarify this.   Logged     The administrator has disabled public write access. #155170 IowaRoadie (User) In youth you learn....

Air and fuel are mixed here , then straight on into the motor. BB   Logged       The administrator has disabled public write access. #155200 IowaRoadie (User) In youth you learn....

It should slide up and snap back nice and smooth too. If it hangs at all it's easy to pull the top cover off and clean up.   Logged     2005 Silverado Chopped KZ   The administrator has disabled public write access. #155335 MS1700 (User) Platinum Boarder Posts: 2585 Re:Is my carb supposed to look like this?? 3 Years, 4 Months ago   It regulates the 'Air' part of the air fuel mixture. I think it is called the Throttle Valve and fits into the 'Air Funnel' Running the seafoam seems to keep it clean on mine. Only cleaned it once in 15K. Much better mechanism than what I have on my auto's the pivot and when they get gunky they don't seal and it causes rough idle and poor MPG. Then I have to use throttle body cleaner and a tooth brush and rags to clean. MC   Logged     The administrator has disabled public write access. #155366 Gram (Admin) Been there, wrecked that.

What does this piece do, and is it supposed to be like that? Just agreeing with everything that has been said so far. That is the slide, it controls the needle and keeps a constant velocity (or near) going through your carb throat. The position in your picture is as it should be when you are idling or the engine is turned off. There is a spring above it that constantly pushes it down, but will let it come up as your throttle opens up and the engine demands more air. As it slides up, it also pulls the needle farther out of the needle jet (the main feeds this system) so that the narrower part of the needle is exposed and more fuel can get into the carb. If you have the air cleaner off, and you rev it up pretty good, you will see it in action. Gram   Logged       The administrator has disabled public write access.
