Gas pedal wont go back

[Hellion]

What is MTL?

Don't forget baling wire and duct tape, bro.

Mountain top lobotomies, I think.

Update. So now I'm still having the same issue even after fixing the throttle pedal. I let off the pedal kart doesn't set at idle. Keeps going. I noticed to get it to set at idle I have to pull the throttle cable towards the back of the kart. Anyone know how to fix this?

Did you loosen the nut for the pivot and add a return spring near the carb?

 

[Blackheart]

I did add a spring. Which didn't do anything unfortunately.. I'm not sure where or what nut for the pivot is sorry

[Blackheart]

Thanks for the pic. Yeah I did loosen the nut on the pivot. Still didn't stop the kart from moving after releasing the gas pedal

Denny is hot on the scent (the scent of trouble). Show us a pic of your engine where the throttle cable connects to the engine. It could be connected directly to the carburetor or it could be connected to the governor linkage (the normal way).

I suspect the idle speed screw could be screwed out too far which doesn't let the engine throttle-down all the way. Show us a photo(s) of your setup. Even if you figure it out, show us photos anyway. It could help someone else in the future.

Here's two pictures of where the throttle cable is connected to the engine

Consult page 25 on this manual. I'm no expert on the OHV engines so the photos didn't make much sense to me. Maybe someone else can decipher.

Might be a good idea to download that manual to your HDD.

My knowledge is very low with any of this. Lol. I'm still learning. But idk if the linkage or gov has anything to do with it.. Could be wrong. All I know is when I let off the gas pedal the trottle cable doesn't retract all the way like it should. Which acts like you're pushing the pedal down not fully just a little

Ok. The throttle cable needs another spring on the opposite side of the arm or lever where it connects at the engine. We all use a spring on the engine as well as one on the gas pedal. I did not see one in your photo even though you said you added one in post #25.

Mninbikes and motorcycles typically do not have two springs on the throttle setup, just one at the carburetor.

EDITED TO ADD: You also must ensure that the throttle cable and gas pedal at the front all moves freely with no binding or friction and it is a very good idea to lubricate the throttle cable inside its conduit or sheathing. You don't want it sticking at any point in its travel.

Oh okay. By any chance would you know what springs would work? I do have some but they aren't strong enough to pull the lever back down when letting off the gas pedal. Also are you saying put a spring in these

 

[Hellion]

Put a spring there, right opposite of the attachment point. The spring has to be pretty strong to ensure it works and can overcome any friction in the setup plus the weight of that heavy pedal. You might have to shop automotive "throttle return springs"...

Oh okay. I'm guessing I leave the spring that's already there. Other end is connected to where you rev the engine (sorry not sure what it's called) however when I look up what that spring us called it says throttle extension spring

There's a spring there already Hellion. You almost drew right over it.
It looks like the governor shaft on the left.

Blackheart. Looks like your kart has lots of patina. There will be many things that are going to be stuck and not functioning properly. But one at a time.

Start at the pedal. Remove the cable. Does the pedal move freely? Here is a good place to put a return spring.
It's not that complicated. Here's one of mine.


Next check the cable. Detach it from the other side. Can you move the cable inside easily?

Follow the path. The part where you just took the cable off. Move it see what all else is moving with it. Does it all move freely? Pivots will need to be clean and lightly lubed.

Getting further around the carb we will need some more pics to be able to assist.

Blackheart and WTR: I think that other spring is a governor spring but I could be wrong, anyway you can tell it is not strong enough. See the manual I posted. Page 26 drawing 16. I hate that manual, obviously written for experienced mechanics and not neophytes.

Question: What is the model number of your engine? Find out.

I'm pretty sure that spring is the governor spring. I've been trying to figure out the model number. I'm not sure but I think it's 1P52F (probably wrong)

Here's the other end of that spring btw

Old bed frames are often full of springs.
