    Wondering what some of you might be using for a hand throttle. A friend of mine fitted a bicycle gear shift lever with sleeved pull cable. The lever is clamped onto the transmission shifter right under the shift knob so its easy to push forward with thumb and push back with index finger. I was originally thinking of something more like a choke cable and pull knob mounted in the dash...but I kind of like this new idea.

    What do you guys do?

    I don't need this but I'm interested in what ideas are out there. :watch:

    Figured you'd be the first with a good suggestion/solution. I don't really need it either...but...
    As the winter comes along, I am going to copy your radio dash hole delete plate with 12V plug and USB connection. Need to clean-up a little bit of under dash wiring at the same time. This project project would fit right in.

    You're giving me too much credit.

    I remember someone here advising against it. Something about the throttle sticking and the Jeep having a mind of its own.

    I put a twist and lock throttle (redneck cruise control) on the dash of the '67 CJ5 (pictured), and a bicycle shift on the steering column of the CJ7. The bicycle shift is smoother, in my case, and I like the "click" adjustment which the bike shifter has. There are better "twist & locks" which combined with good routing would be fine. Actually the routing is to blame for lack of smooth operation, in my case.

    That could be a reality--you want to have confidence in a good, reliable install.

    My '61 has a throttle knob on the dash already. I've seen what your talking about with the throttle on the shifter. Thought this was for slow off-road crawling, could keep feet on the clutch and brake and give a little throttle with this. I don't need this though, mines an automatic.

    The ones I've seen used a bicycle brake lever. It returns to idle when the lever is released. Shouldn't be an issue to cause the throttle to stick.

    I am puzzled by this query. That is precisely what early Cj5s had as OEM.

    That said, twist lock or dial up types can be found all over ebay, from lawn tractors and similar applications. Some have a "panic button" to instantly shut down, such as found on fire pumps.

    Or are you looking for something to substitute for the accelerator, with instantly variable control? Early autos all had hand throttles on the column, as many tractors still do.

    One place where the auxiliary throttle is a real plus is on corduroy roads (rough, wavy) where your foot would bounce up and down on the pedal.

    Not looking for a highway 'cruise control', but for offroad use. On some bumpy trails, I accidentally end up surging the gas pedal up and down as I bounce I around in the seat. I have the floor mounted gas pedal which helps a lot but if I could just hold a nice rpm and focus on steering and use my feet for clutch and brake when needed on sketchy 3 point switchback turns. If I am already shifting from F to R or back, having a finger throttle on the shifter would work well. I would want the throttle to hold position - in other words to not be spring loaded for return. This certainly could be a bit of an issue, but clutch and brake should stop all movement.

    I mounted a throttle from an old lawn mower on the shifter, used a choke cable to run to the carb. Put an eye bolt on the throttle arm, ran the cable thru it and put a stop on the other side.
    Here in Pa there are lots of hills, and at a stop light on a hill everyone likes to pull up on your bumper. with the throttle I can add power and keep my foot on the brake until I can slip the clutch and get moving with almost no roll back. (y)

    If you need pixs of the carb side let me know.

    I ran a set up just like this for years on the 2G carb....only reason I took it off is I switched to an electric one on my Holley carb.

    I used to run 2-finger BMX brake levers on the shifters of my old rock crawlers years ago. They worked ok, but the cables were never the smoothest operators. I had to run a stiffer return spring on the carb to get them to work properly, then it was too stiff for foot comfort.

    I have a factory hand throttle on my 64, but it won't hold, the throttle spring pulls it back in. I hold it for a few minutes when I cold start it to let the motor settle down but that is all. I have a twist lock on my garage motor so I can let it run and warm up and charge the battery, I like to fire it up and run it just for the h--l of it.

    I have the same one as mpc and mounted it on the right side of my steering column with an old turn signal bracket.
    Handy when winching to keep rpms up, and long bouncy hills.

    I suggest mounting the other end to the engine block instead of the firewall. I think the flex between the body and engine causes mine to not be very steady when bouncing around.

    I used a bicycle brake handle and cable for mine. I mounted it on the shifter.
