Gas pedal is sticking and has to be raised manually for engine to stop rev'ing (1 Viewer)

[ouroutdoorfamily]

So I have been noticing lately that after driving a few minutes that when changing gears or just in neutral that my engine is remaining at a rev'd state until I physically lift up on the gas pedal with my foot.... any idea what would be causing this?

Here's a video to show and let you hear

Howdy! Sounds like you have a broken throttle return spring, or a bind in the throttle linkage. Get under the hood and watch while someone else pedals the gas for you. John

HI there,

I had the same problem and I thought a bad pedal spring, throttle linkage and even a sticky cable. I tried to fix all those and then when I was getting my car tuned the mechanic said that it was most likely the butterfly valve in the carby getting stuck. His experience is that as they get old this often happens. He fixed it but it has returned recently.

It also may not be an issue in the states but here in Australia they have introduced 10% ethanol to fuel and the effect this has on small engines (chain saw, mower, etc) makes me suspect this is also contributing to stickiness.

The good news....even if it sticks in the "full down" position most Cruisers will not go fast enough to hurt you.

I had the same thing. It turned out to be the link off the pivot shaft was binding. I adjusted it by loosening the set screw and adjusting it side to side. Worked for me.

Stop making movies, open the hood and figure out what is going on with it.

lol, sorry, I would hate to provide audio and video to help get something figured out. Thanks for the info guys... you to Poser

Yeah it looks like the arm where the accelerator cable attached to the carb is sticking, I don't see a spring that would be loose or wore out, but obviously something makes that arm go back when the pedal is released. I'm running a Weber 32/36 and as mentioned a cable, not linkage pedal

If troubleshooting your vehicle utilizing this medium was your objective, you would provide pictures of the issue.


People are aware of what a engine running steady at a specific RPM sounds like.





I cannot wait for your weather balloon thread and video.





It is not uncommon for the cable housing to fracture where it attaches at the carburetor and for the cable to become frayed and catch/hang up on the damaged throttle cable housing.


I would verify that the cable, isolated from the carburetor, operates smoothly and is not somehow creating your ‘hanging throttle’ scenario. I would then do the same with the carburetor linkage. (yes, linkage; it is on the side of the carburetor)


Set the camera down and get under the hood.

You know, poser, you seem to know quite a bit about cruisers and mechanics in general, however you don't seem to have much experince with social behavior. I used to frequent this forum often, but the last time I was on this forum, six months ago, I was getting sick of reading your cocky remarks & down right rudeness to people asking questions. Today I figured I'd try it out again, & there you are, just like before. Do you ever give it a rest?

Check the spring on the pedal arm.

there should be a spring on the carb like the one pictured.(i know you have a cable hooked up not this linkage but the return spring is the same) if not than thats your prob. next remove the cable from the carb linkage and rev it up by hand and see if it still sticks. if i doesn't stick, it could be you pedal spring. i have had that happen to me once. good luck fyi pics of the carb would be great

I just went through this with my Chevy. Although it's a different breed, it's the same principle. Edelbrock 1405 carb. It turned out to be the throttle return spring was worn out. Replaced it with new, problem solved. It's very simple mechanics. Good luck.

After I climbed into the engine bay and had my wife hold some hoses back I was unable to see a spring as you showed above, and I could not see any type of torsion spring that might be being used..... so.... I solved the problem this morning with a $2.50 coil spring from Lowes and a ziptie, the throttle lever closes now, lol (Not pretty but it will solve my problem in the short run).

INHALER, nevermind Poser, I deal with people like that everyday... they haven't figured out the honey/vinegar thing yet

Here's my hack:

I hate those throttle cables on the weber's they flat out suck. On another note nice job on the engine looks good.
