Carburetor Choke Settings, So Confused
I have a 1983 S-10 with the 2.8L 6cyl.
I took out the carburetor and rebuilt it, cleaned it up, replaced the parts taht needed it and it looks like a brand new carburetor. The truck runs great when it runs, but the carburetor likes to stop it from running from time to time. I found that my problem was with the choke. It's an automatic choke, and I have photo's to help with the question I am asking. It's a simple question with a simple answer I am sure, but I can't find it anywhere online. If it is explained it's not explained with photo's, and I'm a visual learner.
This is the outside when it is intact.
This is the coil (self explanatory)
This is the inside of the casing, as you can see the lever is straight up, and there is a slight hole drilled to the right (it was like that before I touched it). My first question lies with this photo. When the lever is in this position, the butterfly valve on the top of the carburetor is able to be closed all the way. BUT, there is play in the valve, a half an inch to be exact (this was measured from the furthest point from the pivot point on the valve). I think this is usually measured in degrees, but I do not have an angle reader (I should probably invest, no?) So, with this being said, is that much play acceptable? The guide that came with the rebuild kit notes this model engine and year should have the 'Choke Coil Lever Adj.' at 5/64". I am not sure what is being adjusted and from where in this case.
My main question lies here, the other i think i can manage to figure out myself through trial and error. When I am putting the cap back on the lever, and I supposed to place the coil directly on the lever at that position and screw it on tight there? or once the coil is attached to the lever am i supposed to rotate the cap one full rotation? I understand the leaner or richer you want you turn it left or right slightly, but is it supposed to be a full rotation from this start point (pictured above) or slight adjustments from this point?
Thanks for any help, and if any clarification is needed ask away.
