I am working on my '69 F-350 Dual Rear Wheel truck and am having Carburator problems. When trying to adjust the Carb, I could only find one adjuster screw. I soon after decided to just rebuild it. I took it out, flipped it over and verified that there is only one adjuster screw on it. I believe it is a Ford (Motorcraft?) carb and believe it is original to the truck. Is one adjuster screw correct?
Hey, I had issues with mine when I first got it. I tried to tinker with it, in the end I ordered a new one from Autozone or Napa. The new one has two adjustment screws. I had a friend of mine adjust it for me. I had problems getting it just right. It would stall at stoplights. It seems to idle low now but its the only rpm that will work in any condition for the 360 and auto trans that i have.
If you have a 360, it would have originally come with a autolite/motorcraft 2100 2 barrel carb. It would have had 2 idle mixture screws. Of course, after 43 years, the original carb may have been swapped out for something different. Best to post a few pics, then it will be easier to identify. You should also make note of any numbers located on the metal tag which will tell us exactly what you have. This metal tag may also be missing...
