Spid Question
I found this truck for sale and the owner sent me pic of the spid. I see the code for "Manual Throttle" and my question is, by 1971 didn't all the trucks have an automatic choke on them? With that being said maybe a "Manual Throttle" was available because, depending on what you wanted to do with the truck, you may need it to stay revved up for sustained periods.

Re: Spid Question

Re: Spid Question
I like to call it poor man's cruise control. As explained it is a dash controlled cable that will maintain a set throttle position. I would use it like cruise (the speed would just go up and down depending on hills, wind etc.). Cool Option!

Re: Spid Question
The manual throttle had nothing to do with the choke. For some reason i have seen quite a few manual throttles on blazers. And yes, it just held the throttle at a certain rpm.

Re: Spid Question
My 72 4x4 has the manual throttle. Farmers used them because it turned feeding the livestock into a one man job. Set the throttle, put trans in low gear and throw hay bales as truck eased down the feed line.

Re: Spid Question
They were also common on trucks that carried campers. It would be used to chearge up the battery(s) and/or to keep the coolant heated up if the owner added a second heater run off the engine cooling system. This truck looks like it may have been optioned for camper duty.

Re: Spid Question
The option is discussed in my `71 owner's manual.

Re: Spid Question
I would think most anything that has a PTO should have one.
My wrecker of all things did not come with one but had one added when it was converted to a wrecker by that company. (truck was a cab/chassis from factory)
