Hello, new here to the forum and have already picked up a lot of good info before my first post. Long story short, got a 63 uni hand-me-down from the grandpa, he wheeled and dealed it off someone so no sentimental value to him. Had the truck about a year and a half. Pulled it out of his field, got it home, threw some gas in the bowl and fired right up. Can't kill an inline 6. Eventually I sold it. Then I bought it back. Got it running, drove it, broke down, parked it and let it sit for a while. Now I got my motivation back and I'm trying to finish it out. It will never be an all original truck but has great potential to be really nice. I've ran through all the fuel lines and found a tank and seat out of an old dump truck. I'm still having problems with getting the idle set on the carb. Carb has been rebuilt and I stay away from ethanol. When I do get the idle set, it will idle all day, but when I drive down the road and let off the gas coming to a stop it wants to die every time unless I have the choke pulled out a certain amount. Can anybody throw a dog a bone on this one. I have plenty more questions to come but first things first. Thanks
If you have a tach, the Idle should be at 500-550 for manual transmission, and 475-525 for automatic. When you get it to Idle have you adjusted out the idle mixture? If so check that the chock lever is making the choke plate all the way open and is verticle. If it is not loosed the screw that retains the chock cable, push the **** all the way in. Move the lever to ensure the chock is all the way open and tighten back up the cable lock screw. Then adjust the idle once again, and the idle mixture.
A couple of things to check is carb tight to manifold and loose throttle shaft in the carb base, this causes vacuum leakks that will make adjustment difficult.
