Go kart question.

[yerf_dogger]

had the same problem.

all you need to do is clean your torque converter, both driven and driver.

check the springs and weights to make sure they can move freely.

also change that belt. if it is less than 3/4 wide its just gonna slip and jerk.

the driver has to open up to wide to start your cart and bogs down most likely.

here is a cleaning video and a link for a new belt

That's funny. That video is not only available right here through our site, but was shot and posted by one of our moderators, Blazkowiez. Have a look here- http://www.diygokarts.com/vb/showthread.php?t=7332&page=1

That's his write-up on the subject.

Your driven clutch looks like it is stuck open. That would explain having no bottom end.

Stuck open?
I don't understand.
When the its spins the weights make it draw in to grab the belt, is this not normal?

 

[Knight]

The clutch on the motor is the primary, the secondary clutch is the other one with the chain behind it. The secondary clutch is stuck opened, the belt should be all the way at the top. Try a good cleaning of the secondary, the side with the spring should move in (together) with the spring pressure pushing belt to top. The sliding surface may be gummed up, not allowing it to push belt up to top, thus not low gear. When you get it moving freely you need a new belt, try with old belt first.

Ok,
I got a new belt. It's wider and working real good, we still can't punch it from dead standstill.
When you say primary and secondary clutch, are you meaning the same thing as theb driver and driven pulley?

 

[Grimace]

Yes. Your drive pulley should start out small, and squeeze together progressively making the groove larger with centrifugal force caused by engine rpm. At the same time, due to the same centrifugal force, your driven pulley will open up and get smaller. This action makes the kart go from low gear for torque, to high gear for speed.

This is a pic of how the pulleys should look when the kart is stopped and the engine is at idle or off. When you are at full throttle, the belt will be in the top portion of the drive, and the very bottom of the driven.

How do I get it in alignment?
What steps do I take?

 

[Grimace]

First I would address the issue of the driven clutch (pulley) being stuck in what is referred to as high gear. That means it is stuck open. I would take it off, take it apart, and clean it very well removing old grease/grime and rust. Then I would go about adding/removing shim washers to get the belt in line with the drive and driven pulleys.

 

[yerf_dogger]

also make sure that the inserts on your driven clutch arent wore out and not floating in between the cam.

I didnt turn my cam clock wise and put the snap ring in place the proper way and had similar issues once I finally got it all back together.

its kind of a pain but makes a big difference in performance.

still sounds to me like it needs to be taken apart and cleaned real good

I agree 100%.

 

[Sparky723]

Ok, thank all of y'all- but I'm really confused.
Is there a difference between the driven clutch and the drive driven pulleys? I'm totally lost as to what pieces I need to pull off and clean and align.
Do I need to watch a video, read a link, get special tools or knowledge?
I'm pretty handy with things, I just need to have help getting started.

 

[Grimace]

The driven pulley is the driven clutch. Yes there are threads about clutch cleaning, just do a search for torque converter maintenance.

I would suggest that you go on over to the FAQ section of the forum and have a look at the Helpful Links sticky. There are several articles/websites/threads regarding your Comet CVT. I suggest you read them to find out about the workings of the clutch
