Carb prob?
I have a 1985 f250 stick with a 302. Lately I have to choke it(manual choke) to keep it running at idle. Do you think its a carb problem or something like a vacuum leak? I looked for obvious problems and see nothing. Thanks in advance for any help.

What kind of carb? A vacuum leak would almost always cause a fast idle, like when you pull out the PCV. Actually try that, pull the PCV out of the valve cover. Does the engine speed up, if so you just need to adjust the throttle idle screw.
