Hello everyone,
Hoping to get some help tuning my stock carb on my Automatic 1980 D50 2.6L w/AC. I recently put in a new motor and sent the carb to be rebuilt. When I first got the truck, it was not in running condition due to someone blowing up the engine. Rod shot out the block. I figured it would be a good idea to have it rebuilt since I didn't know the condition of it or how long it was sitting. Right now the truck idles when cold, albeit rough, but drives fine. I am able to drive it if I keep my foot slightly on the gas with rpms at or above 900. when warm it doesn't like to idle and will stay idling very rough for about 10 seconds before dying out. Will start right up, with help from a little bit of throttle, afterwards. I was wondering how I go about even starting to tune the carb and how to identify the SAS screw and Mixture screw mentioned in the service manual. Is there a certain number of turns for each screw that I should start at? I really want to get it running and since I'm in California, I would like to keep the stock carb. I'll attach a picture of the screws I can see.
