Honda gx120 4hp throttle help

[ramairgtz]

I bought a honda gx120 motor for this kids kart, got it all hooked up and i can't change the throttle with the lever. I noticed that the butterfly in the carb is stiff and hard to turn. It came off of an air compressor and I think the throttle is supposed to be set and left alone. The one on my gx160 moves very easy is there any way to loosen it up? I pulled the carb off and sprayed some wd40 around the shaft and it's alittle better but not much.

there is a bolt that holds the lever on if u loosen that bolt it may be the issue
or clean the carb as something may be sticking

I already loosened the nut on the throttle lever and added another return spring so all that is good. The shaft that turns the throttle plate in the carb is the one thats very stiff. I soaked it with some pb blaster last night but it didn't help. Here's a pic of what I'm talking about

Pic is working for me? I cleaned out the carb last night and it didn't help. I'm going to try to take the butterfly off the shaft then pull the shaft out and see if I can clean it up

I pulled the screw out of the butterfly and took the shaft out and there was some kind of stuff wrapped around the top of the shaft. Didn't look like a seal or anything so I pulled it off and now it moves very easy. I guess I'll put it back together when I get home from work and see what happens.

I didn't realize the throttle was stuck last night and I started it up and it took off across my garage

should work
i know the pic works for everyone else
it is cause i live at a boarding school and they block things on the net

Going to put it back together in a bit and see how it works. I looked at a diagram to see if that was some kind of gasket but didn't see anything.
