85,ranger,
My '84 did this all the time I switched it over to the older distributer and carb and that took care of it. I have heard others who had this problem also, but am not sure what the fix was. I used to be able to drive it about 2 miles and then shut it off for about 5 minutes then it would drive fine the rest of the way to work, but if I tried to go straight to work on wet days it would run like crap all the way there. It was very annoying. so you are not alone.

85,ranger,
I've read several posts & replies that refer to the tendency for these old carbs to get condensation (& icing in cold weather) rather quickly & easily. Mine does it too. Shutting off the engine after 5 or so minutes of running, as mentioned, allows heat from the exhaust manifolds to rise into the engine compartment, to heat up the air cleaner & everything else, and evaporate any condensation that had begun to occur. One thing to look for on vehicles this old is the vacuum diaphragm that opens & closes the warm air control on the air cleaner snorkel. The diaphragm eventually leaks, thus failing to open the warm air flap. The carb never gets warm air, and forms condensation pretty badly. Even when the warm air control IS working, you can get a little condensation on REALLY DAMP days (100% humidity at around 35 to 40F). But if the warm air control is working at all, it should clear itself up in a couple minutes. A little alcohol in the gas helps alot too (gas line anti freeze).
