Problem with rod carburetor and accelerator cable

[luc.tor]

Hello all friends,
I replaced the accelerator cable and the rod near the carburetor but now if I try to move manually, the rod lowers instead of entering compressing the spring.
Did I do something wrong?
I attach a short video: https://youtube.com/shorts/vhUedJ4vDPU?feature=shared
Thanks! 😉

That set-up is made to work when the accelerator cable is pressed by the driver !!!

I would ASSUME that moving it by hand would do just as your video shows.

if you want to throttle up from the back of the engine compartment > push the cone thing over the cable back some . now it shouldnt bind like that . ?

the only thing you did wrong was your TEST , go try with the gas pedal and make sure nothing binds and you should be good to go ........

My take on what's going on is, The fan shroud throttle cable tube is rising out of the fan shroud. Instead of staying against it and it should.

If the throttle cable tube flared end is against the fan shroud, you should see the
return spring from the fan shroud to the carb tube with the spring retainer inside it.
We can't see the spring, so IMO it is assumed that the FS tube is floating out of the FS.
Place a hose clamp on the FS throttle cable tube between the FS and the forward fire wall. That will hold the FA tube in place alloying the carb return spring to function correctly.

The action/motion you are putting on is appropriate, but in addition to others concerns I think your barrel nut is too-tight. That barrel nut should rotate freely. It may be as simple as the diameter of the barrel nut you have installed is a bit too thick, or you could swap it out for the correct style barrel which sits inside of the arm rather than through it.

You want to avoid bending the cable like that, or it will break the cable there.

If you need to rev up the engine once or twice, grip the cable just at where it comes out of the tube spring setup. You want to keep more pushing pressure against that slotted fastener that goes up against that swedged on end on the rear of the cable.

If you are doing a lot of tuning needing reving up, then loosen the cable clamp and let that slide on the cable swedged end.

The video link in the original post doesn't appear to be working. But from the descriptions I take it the accelerator cable is binding up in the area between the carb and the tube the cable passes thru the fan shroud?

Question... the cable should move freely thru the entire length of the accelerator cable tube that runs thru the tunnel. I seem to recall when I disconnected the cable from the barrel nut in the carb linkage the cable would want to pull and retract into the fan shroud tube. This was because the accelerator pedal has a small spring at its base to maintain pressure on the roller wheel. This small spring is too weak to fight the carb linkage return spring, but when disconnected it should be enough to pull on the cable.

When you disconnect the cable from the carb does the cable want to retract into the tubing? If not, check into why? Are you missing the spring at the base of the accelerator pedal? Is the linkage at the pedal all gummed up? Do you need to clean/lube your accelerator cable more? Is the flexible section of the tube between the center tunnel and the fan shroud (near the transmission) not seated properly or missing?

Hello friends,
First of all, thank you so much, you were fantastic in your answers!
Thanks for your help

In the meantime I made a small adjustment which I explain below and I took new photos to explain myself better.

Below I put the replies to your messages and the new explanation.

Today I slightly loosened the cable fixing screw on the carburettor and this is currently the situation:

View from above (always at rest or without pulling the cable):

Here, however, I am manually moving the carburetor and the cable instead of going towards the fan, curves downwards:

In this photo I added some arrows. I pull down on the carburetor and there is a point where the cable bends and goes down as the arrow shows:

Is everything normal? Can you tell me if this is the case for you too?
Thanks friends!!!

Found these pics in another thread:

From the pics it looks like there should be little to no flexible cable showing out the end of the sleeve. The spring takes up all the cable slack and pushes the sleeve all the way up to the ferrule at the end of the cable.

Also, there should be a flange or washer that points the tubing up at an angle so there is no reason for the cable to flex (top pic) as it is a straight pull into the tube. Your tubing appears to be coming nearly straight out of the fan shroud. Maybe you have the wrong fan shroud, or need a new hole with a steeper angle that points directly to the connection point on the throttle arm?
