on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Oct 2005 Posts: 738 Shop Shark | | Shop Shark Joined: Oct 2005 Posts: 738 | There is a little knob with a "T" on it on the dash of my 61 chevy. It used to work as a kind of hillbilly cruise control, until it stopped working. I actually used it more to warm the truck up than anything else, I would put the gas pedal down a touch and lock it and let the thing warm up. A month or o ago it quit working. Is this knob a driect cable assembly? Meaning when I pull the knob does it literally lock the carb in position, or is it attatched to the gas pedal. I would like to fix it because it worked as an effective cruise control on flat ground and was a nice tool to warm the old truk up without sitting in it. Thoughts, ideas, verbal abuse, all welcome.

Patton My Machine | | | | | Joined: Feb 2006 Posts: 2 Junior Member | | Junior Member Joined: Feb 2006 Posts: 2 | sounds to me like a throttle control like on a tow truck. We just put one on. Does your truck have an extra cable running to the carb? MY does. You pull it and turn it 90 degrees to lock it. Thats the only wat i know of. You can get new cable kits from aw direct towing. I have a brand new adapter kit (if yours hooks up different) that i did not need.If you would want to go that route let me know.

the throttle was intended as a way to up the idle for running PTO things, as on Johnny's tow truck, or for the warm up you do, or to hold a very slow granny-low crawl in the farm field pickin up the hay bales - VERY unsafe thing to use as a cruise control considering there's no automatic release in an emergency

I covered mine w/ heat shrink tubing and am able to use a motocycle cable greaser to 'lube' the hard wire 'T'. the luber looks like http://www.motorcycle-parts-and-acc...able-lubricator-black-gold-prod3257.html about $10. @ any good m/c shop in town.

As Red points out, it would be useful in the larger trucks with PTO's for running the pump.
A '66 is 20 years into the future, so technology could have changed things.. but in '46 the 'T' knob is connected to a cable the same size as you'd find on your typical lawn mower throttle cable, and connects to the throttle on the carb.
I can't imagine it would be a real accurate, reliable, or safe cruse control, tho.
an idea is only stupid if you think about it rationally.

Bill | | | | | Joined: Oct 2005 Posts: 738 Shop Shark | | Shop Shark Joined: Oct 2005 Posts: 738 | cool beans, thanks for the replies. i do not use it for cruise control...it is tempting at times though. anyway thanks for the info.

You can turn the knob slightly to "lock" it in place.

There you go trying to be different. When I was driving semis for a living (the 70s) we used the throttle as cruise control. I was even known to put my foot on the dash to stretch out. But I only did that on lonely stretches of highway, like in western Oklahoma.

When I used to use mine the lube helped get the thing moving. In other words it was rusted or stuck and that helped. I also think the friction that would still be there is enough to make it work as a very primitive throttle cruise control, but it would slowly drop in speed.

It is just a stright pull out like the choke. Fred, I like your style, I knew I wasn't the only one who had done this. There are not a lot of flat spots where I live, it is known as the "Rolling Hills" so I am kind of SOL there, but if I were a Kansas resident I bet it could be used a lot. Thanks for the posts everybody.
