Lazy Throttle Cable

[ANTPER 207]

Hi Folks

Have a throttle cable lever style that doesn't like staying at full power and drop to half throttle very easily while running. Usual they are stiff and bind up. Never seen one do this. Any tricks of the trade on getting that cable stiffer and not drop down on its own. Or bite the bullet on new cable? TIA.

Both my rigs do same thing.  Can’t wait to find out the solution!

Use a vise grip to tighten the rivet that creates the friction on the lever.     If that doesn't work, drill out the rivet and install a bolt with a locking nut.  Then you can adjust the friction.

I have a couple pull type cables that utilize clothespins for cruise control.

HaHa this is my first experience with all the tractors I've owned. I even tried crimping the outer cable casing to cut down and the ease of the sliding. Didn't help.

I'll have to take a closer look at the assembly and find those rivets. I'll keep posted on results. Thanks!

If you do decide to go the “replace rivet with bolt” route (which I firmly recommend). I’ll offer two suggestions:

- when you take apart the control there are several different kinds of washers layered in there with the lever and the bracket. KEEP CAREFUL TRACK and put them back in the same order using the bolt.

- I used a shoulder bolt--one that is not threaded all the way--of the length I needed (Hillman drawers at the good hardware store) That way, the throttle lever is pivoting on smooth metal and not threads--it’ll last longer since the hole won’t get worn larger.

Ditto! Never had a problem since doing this.

Had a tractor that did the same thing and then realized it was a twist and lock style.pull it out to your desired speed and try twisting it about a quarter of a turn to see if you have this style as well  round knob usually. If it's a up and down type there is usually a small nut and bolt you can tighten up to prevent it from costing back

Folks

I took a pair of needle nose vise grips and set it to as tight as possible and clamped down hard on it and appears to have worked? If it loosens again I'll revert to the bolt recommendations. Thanks again everyone for responding. Going to my first W.H. show in a few weeks and looking forward to meeting some of you there hopefully.

Or try a larger pair of vise grips if you have one.  Knock on wood, that method has always worked for me in the past, but the bolt plan is an excellent plan B that should work just fine.
