I have not received the carburetor rebuild kit yet (due tomorrow) but I thought I would break it down, and take a bunch of pictures to get ready for the rebuild. I found that the throttle cable (from the throttle knob inside the cab) was broken and was not attached to the carburetor. The choke cable (from the choke knob inside the cab) was still attached and working well.
When I got the carb off, there was a small puddle of gas in the bottom of the intake manifold. I'm not entirely sure what that means.
Carburetor off and disassembled:
I blew out all the passages and used a carb cleaner to get the bulk of the gunk cleaned out.
The carb was surprisingly clean. The gaskets also looked pretty good. The lower gasket had a tear and was pretty worn, but didn't look too bad.
So I reassembled the carb and put it back on to give starting it another try. Sharon helped me again. With the carb fully choked, we got the truck to start and after some rough running for about 3 minutes the engine warmed up and we were able to close the choke down to about 1/2. If we closed the choke down below 1/2 the engine would stop.
Even after running for 5 minutes, we could not get the truck to start or run without 1/2 choke. I tried adjusting the idle, without any success.
I'm wondering if the broken throttle cable has any effect. The gas pedal still works, but the throttle cable may work in conjunction with the gas pedal in some way I'm not seeing.
I think I am going to have to bribe some of my more knowledgeable friends to come over and help me understand how it all works.
