Gearing issue

[Hellion]

The motor was sputtering and not running great

Well they do that sometimes and they will do that eventually. They are somewhat finicky machines and love good, clean, quality gasoline and decent care.

You can use the old engine to learn on. They are tons easier to fix than modern cars with their electrical gremlins. Oh by the way, better get your socket and put it back in your toolbox.....

Yeah no that socket is stuck stuck I have to figure out a way to get it off.

Pics.

Both ends. A good pedal shot, the adjusters, and some of the carb side.

You need a return spring.
There are many ways to put one. We can advise how when we see.

Does the eye of the cable (yellow) swivel under this bolt or is it locked down tight. It should swivel for best operation. Use a nylon lock nut or 2 regular nuts jamed together.
If it does swivel now then you need to take up some slack with the adjustors.

You can also move it up a hole for more travel if needed like I mentioned above.

I also would put a spring here (red) to pull the pedal back.



Did you losen this 10mm nut? The plate under it should swivel freely.

No the cable eye doesn’t swivel I wasn’t sure about that so I just made it tight I can change that. No I didn’t loosen that 10mm bolt. What exactly is it for? And for the spring what type of spring would go there and bring the pedal back? If I a regular spring in there it will push the pedal away instead of inwards.

 

[Whitetrashrocker]

They make pull springs too.
Kinda like this. The long hooks make it easy to go around the bracket.



That 10mm nut holds the throttle linkage. Its has some tention on it from the factory to hold the throttle position when used on a power washer or water pump.
For go kart use, you want it loose so the throttle can return to idle.

Okay thanks for the advice I’m on the east coast so I will have to wait for this weather to pass before I get back to fiddling with it but I’ll post back here if I have more issues.

absolutely not the amazon special 3 for the price of 1.

Those belts are a problem for everyone that uses them.
there is a reason comet belts cost more...

WTR, you have kind of taken over the instructional role. So I will address this to you. On the video of his torque converter, ( limited view ) but that chain looks to be very tight. Especially after he said the chain was smoking. I have never seen a chain smoke before. No pun intended. The CVT seemed to be working in the video, but go to post #41 and expand. Something on the driven doesn't look right.
Can't tell, but are the plastic stops missing? Almost looks like the point of the cam ( dead center in the picture ) is stuck behind something. A brand new 224 with a CVT, that thing should push you back in your seat when you nail it.

Pancho,
Im not taking over duties. You guys just left me unsupervised. You can drive if you want.

I posted a Pic of proper chain tention.
I can see the cvt has at least 2 buttons and its clocked properly. It seems to function normally although theres some small things that need addressing. Like that stuck socket and the ringing bracket thats loose behind the driver. I would also polish the sheaves while it was apart for maintenance. Which I also mentioned.

Your right about this set up, it should haul mules.

Keep at it Manco285, we'll get you going.

You're doing great...carry on.

Manco typically uses two throttle return springs, one at the pedal and one at the engine. It would behoove us all to emulate the factory throttle setup with the proper hardware -- scope out this parts manual:

https://landmaster-assets.american-landmaster.workers.dev/uploads/manuals/Fun-Kart/285_operatorsmanual_2851628518285162285182.pdf

Note where the pedal is attached to the frame (bottom hole) and the throttle cable is attached at the hole second from the top. The bottom bolt #78 is a shoulder bolt meaning it has a smooth unthreaded portion. The eyelet on the throttle cable rides on part #75 which is a bushing. This bushing ensures the cable eyelet stays loose when you tighten nut #44. The rest is fairly self explanatory.



Those return springs #87 and #88 are readily available online. The springs are critical for the engine throttle, less critical for the brake.

For example: https://www.gopowersports.com/manco-brake-throttle-pedal-springs/



I know there was a jest made that flew over a few heads, but whoever is online feel free to assist and answer any questions. Multiple eyes and brains are better than one.

Also, forgot to add: Lube your throttle cable regularly. Use something GOOD, not a quickly evaporating solvent like original WD-40.
