try lubbing it, i would add a spring though for sure. just attach a spring to return it to the closed position, almost any small spring will work.

There could be several reasons this is sticking, you could have something on your throttle arm, your butterfly, your linkage, your cable itself. Please take pictures and try to examine the operations of your throttle while someone else pushes the pedal.

Actually, did it ever stick before? did you hook up the throttle? If so i think u just need a spring, but always check for something in the way.

A spring on your butterfly is not always the answer and often can damage the carb. Take pictures and show them to us, if this is a Tecumseh and was meant for a go-kart it already has a strong spring and a linkage return kit, there are reasons things stick, we must fix these problems and not just simply "throw another spring on there". Come on people, what happens when your second spring gets stuck?

it could be your throttle cable is frayed on the inside. Thats how both my karts were, i just used a spring, since a new cable was $32......

That's assuming he has a spring already, he didn't say. Coulda broken, come off, new installation, etc. Let's find out, first...

Now THIS is what we want to avoid!
If a throttle cable is $32, you're shopping in the wrong place.
If you decided you couldn't afford brakes, what would you do?

Brakes went out- I'd use my foot on the pavement like before ha :)
It was a manco cable, with an eyelet, 76" I believe

i went to a local bike shop and bought something like 70" of brake cable for $20 and felt like i got ripped off.
