Hey,

I figured out my idle issue. The clutch is too tight, causing it to go off on idle. How do i extend the length so the belt doesn't get caught on idle?

Do you mean the chain? (or you seem to be using a belt). Please provide some more info on your setup. Pics would definitely help too.

What you have got to do is tell us what TC you have. If it has a backplate (Comet 20 or 30 series) you will just need to get the correct belt for it. If you do not have a backplate (like a 40 series comet) then you need to measure the distance centre to centre between the driver and driven, and then buy the appropriate belt

Have a look at these first.

Ok, The TC is a TAV 30 TC. The belt is correct, it's brand new. The clutch is a LITTLE bit too tight. This must be due to the shop i took it to.

Are you sure you have the right belt? Have you got a backplate?

What do you mean about the clutch being too tight?

I'll take a picture. I mean the two pieces that are pulled together when the gas pedal is pressed to make the go kart speed up. It's already touching the belt instead of letting it spin. This is definitely the issue. The belt is exactly like my old one, which never had this problem. (I'm thinking the people at the shop did this:ack2:)

Take a pic, but if you think the kart shop is the problem, I would take it back and tell them that it is not working after you got it back from them

Your idle may be too high. If you can lower it, see if that helps.
Your spacing between the engine and the jackshaft could be too far apart. That's why we need to know if there is a backing plate. If there is no backing plate, adjust the engine so it's closer to the jackshaft, leaving the belt a little loose. You can check this without the motor running by pushing the kart forward and observing the drive pulley. It shouldn't rotate when you push the kart.
Again, a picture would help.

No way, they're terrible. They are the worst people to repair a Go-Kart.

Here's a picture...

Are you sure that the belt is the same? Does it have the same number? Yours says 12-8487. Did your old one have the same number. This belt is meant for a 6" driven with a center to center distance of 6-15/16 to 7". Is yours this distance, or is it something else?

Yup. Is it possible that they tightened it too tight?

No, I don't think so. If it is on a backplate, you can only install the driven and driver one way. They cannot be closer or further away from each other. That is what the backplate is for. It maintains a predetermined distance between the two. Could you take a pic of the driver and driven in the same pic from the side and the top?

On the driver (on the engine) look where the belt rides. Is there a bushing on the driver shaft, or is the belt riding right on the shaft?

May or may not help, but on my Burgmans CVT if you tighten the plate without wiggling the belt at the same time you end up tightening the plate against the belt and it won't work right. You'd think the belt would eventually work its way out, but it doesn't (at least it doesn't on the Burgman). Loosen your bolt and wigglle the belt, tighten it a bit again and wiggle the belt. It helps to squeeze the middle of the belt together (literally - the part between the pulleys) when initial tigtening. The belt should always be able to be rotated (though it may be difficult).

I fixed it. Just took apart the clutch and added grease. I must say this thing flies.
