Manual Choke
Hey. Just bought a 1970 C10 about a week ago. By far the oldest vehicle I've ever driven. I had never used a manual choke before. Here's my question. The choke cable is connected to the exterior choke lever on the carb. From inside the cab it is extremely hard to pull the choke or release it. I usually just end up popping the hood and doing it with my hand. Any fixes?

Re: Manual Choke
You will probably need to use graphite lubricant on the cable itself. Welcome to the site, good to see another Utahn on here.

Re: Manual Choke
You might try removing the cable, holding it in a manner that it will gravity feed, and shooting WD40 down the cable and letting it soak.
In case you've never run a manual choke before, there are two steps (when cold): 1) Pull the choke all the way out 2) Turn key 3) As soon as it fires, you push it in about 1/2" or so, based on feel to where it runs the best A carb does this automatically with a vacuum powered "choke pulloff", but you have to do it by hand. So it's not a set it and start, it's a set it, start, then reset it.

Re: Manual Choke
Can you post a pic of the hook up at the carb? Also how long is the choke cable. I think mine may be too long. There are no sharp bends in it but it is looped a little bit. Thinking about the wd40 method and maybe shortening it a little so there's less bends.

You forgot a couple of steps: 1) Push accelerator pedal to the floor 2) Pull the choke knob all the way out 3) Let up on accelerator pedal 3) Turn key 4) As soon as it fires, you push it in about 1/2" or so, based on feel to where it runs the best Pushing the accelerator pedal to the floor before pulling the choke knob out sets the high idle cam to keep the RPM up while the engine is warming up.
