While installing my carbslide I realize its hard to go down, and when in it does not slide. WHat could be the cause of this? What can I do? I was thinking I might need a whole new carb?. Below is a picture of how the thing looks
I cant really see it, but I have to apply some real pressure to it to make it go down. At first I thought had to. THen i realized that that was the idle, and it had to move up and down freelly, upon taking it out I messed up the throttle cable, so now im not to sure, I noticed the little hole on the bottom of the barrel,, however when you release the spring it should make the needle straight, so it can line up. the carb slider did go down, so i belive that that is indication that the needle does line up, but my question is why isnt it moving freely up and down, when i first took it out it was free, I doubt i bent anything, I was pretty careful. so any advise.
The idle screw is on the outside of the carb, usually on the left side. It is flat bladed, with a knurled edge so you can easily turn it with your fingers. It has a spring under it to keep it from vibrating. The tip of it protrudes into the carb and keeps the slide from going all th way to the bottom. Turning the screw changes how high the slide sits at idle, thereby changing how much air and fuel go into the engine. Basically, it is like holding the throttle a little bit open. To adjust it you screw it in for a higher (or "faster") idle, and out for a lower (or slower) idle. When you get your engine running slowly screw it out to lower the idle to where it just runs smoothly without dieing.
one more thing. put a couple wraps of teflon tape around the throttle barrel before you screw on the cap. don't overtighten or it makes the barrel smaller causing the slide to stick. mine was sticking and I loosened the cap just a tiny bit and, whhhut, the slide dropped to the bottom. my .02
