It was the strangest thing

So I went out to try out my 68 this afternoon, which has not been driven in the last few weeks due to the large amount of rain. I started it up only to find that it will not stay running at idle. If I rev the motor it will keep running, but as soon as I take my foot off the gas it dies again. Any ideas?

maybe clogged fuel filter? happened to me before, same problem.
Take the air cleaner off and check to see if the choke is closed when cold and fully open after warming up.
How old is the fuel tank? Possibly something in there clogging up? Also could be the clogged fuel filter or maybe a pinched fuel line. My 67 was doing the same thing and I had a pinched fuel line, I guess it happened when I had the new floors installed and the sub frame connectors put in.
All good leads. I guess I will have a new weekend project now to go along with the tranny rebuild and building of the new motor.
Perhaps the carb bowl supply has evaporated and left a varnish that is causing things to stick.
Heck, it's as good a guess as I can make right now.
Check the vacuum hoses.. sounds like a vacuum leak to me. Maybe?
My vote goes with Fastbacker on the vacuum. Check the hose between the carb and the valve cover. Good luck! /forums/images/icons/smile.gif
Vacuum or junk in the idle circut. Possibly the throttle isn't returning all the way.
