doesnt move when i press the gas peddal

[Chris19]

there is a kind of wire that is hooked up to the pedal and runs to the motor. but the problem is when i press the pedal i could see that it pulls the wire but not enough to make it go. i dont really know how to explain it but there is some kind of lever that is on the motor, and the wire is hooked up to that lever and it wont pull it but if i pull it with my hand the kart will take off and ive taken the wire off completely and put it back on and that had no affect and i dont know what else to do but ask on a forum.

At least you've tried, I hate people who don't even try to work something out for themselves first. Take some pictures of the setup and if it's a branded kart tell us the name of it.

A picture of where the cable goes at the engine end and the pedal end would work, maybe one of where it goes in the middle. There could be something pinching it you havent noticed

 

[Chris19]

ok ill go take pictures now, but the go kart is a yerf-dog 32001. the go kart is one of yerf dogs old models so i expected problems when i bought it.

 

[Chris19]

the photos are in order from the pedal to the engine

Try to find where the fault lies. With the engine off, keep moving the pedal up and down while watching the cable, and the lever on the engine. And if you move the lever on the engine by hand, what is different?

Make sure that the conduit (the black sleeve that the cable (wire) rides in cannot move at all. If that sleeve can move, it will cause your problem.

 

[Chris19]

the black sleeve moves around the middle when i press the peddle but not a lot, but if thats the problem how can i hold it down so it doesnt move? ive held the sleeve tightly againts the bars so it doesnt move and it had no affect. uwhen i press the peddle it will pull the lever but hardly, not enough for it go even give gas

 

[Doc Sprocket]

For starters, you've got to stop ALL movement of that cable sleeve. Zip ties (aka cable ties) might prove very helpful. If, after you have rendered the sleeve perfectly motionless, you are still not getting enough cable pull, we will examine other possible causes.

EDIT- Did you rig the whole mechanism, or did you get it like that? I bet your leverage is off...

 

[Chris19]

also i was thinking that the cable could be to long so when it pulls it has extra cable that is being pulled as tight

i got the rig like this, i havent added anything to the kart except for front and rear lights and a battery to power the lights

 

[Doc Sprocket]

Okay- regarding the "long" bit- look closely- when you begin to push the pedal, does the cable start to pull at the engine side nearly immediately, or is there a lot of slack?

 

[Chris19]

yes it pulls as soon as i push.

the weird thing is that yesterday i rode it with no problems, i turned it off to get a bottle of water, turned it on and wouldnt go.

also when i took it off the lever i pulled the cable and an inch of cable came out

From pics 2 and 3 it almost looks as if the liner is coming out of the insulation sleeve. Using your hand to press on the throttle watch and see if the lever on the engine moves in its full range. Could just be a matter of a stretched cable.

 

[Chris19]

jonboy im sorry but im new to all of this go kart stuff and i have no clue what linner is, and i didnt understand anything you said. can you repeat it in a newbie way but not that newbie

 

[OzFab]

Ok, let's dumb it right down: That wire is your throttle/accelerator cable. Pulling it moves the throttle on the carby which makes you engine rev &, in turn, makes your kart go (as you found out).

If the engine is not revving by pushing the accelerator pedal then the cable is too loose & needs to be shortened or, possibly, replaced.

Looking at picture 2, there is a bolt/screw which I will assume is the cable retainer, this holds the cable in place by clamping on it; you need to loosen this & pull the cable through until there is no movement in it. Don't pull it too far or you will move the throttle linkage, just enough so there's no slack in the cable. Once you've done that, tighten the retainer screw & you should be good to go

 

[Chris19]

thanks man that made A LOT of sense at first i thought of that but i was just going to see what you guys say. ill try it out tomorrow and post the results

 

[jonboy]

Thats cool dude. Not a problem, I've been there too. Your cable has a series of parts actually. The black part on the outside is what is typically called the insulator. The insulator is usually molded or adhered to the conduit or liner to keep it from picking up any electrical current. The cable moves within the conduit liner. Sometimes the liner comes undone from the insulator due to a bad cable inside it, worn or age and causes it not to work or move proper. Usually what I have seen is the cable get bound up and the liner pulls out of one end. Hope this helps give you an Idea of what I was talking about.

 

[Blazkowiez]

In the 3rd pic you've got your governor jumped with the main spring, however I will say the cable just looks like its stripped on the inside. It most likely isn't grabbing for all the way, the correct threaded end cable can be purchased from any Rotary supplier for 10-15 dollars.

? Seriously? It's not intended to carry an electrical signal....

 

[jonboy]

Seriously! The insulator is to PREVENT it from making contact or arcing out.

I'm honestly not sure if you're serious or just trolling?

For God's sake its a cable you pull on not an electrical cable

 

[OzFab]

... but, if the outer insulation happens to rub off & contact an electrical wire, nasty things may occur: It's called a short circuit
