I'm having some trouble keeping my 67 stang running for more than about 5 secs. When I pull on the throttle linkage, plenty of fuel squirts into the carb throat. I've tightened everything down around the carb to aviod a vacuum leak. The only other thing I can think of is that the timing is off. It's been a while since it's ran and I didn't think timing could be thrown off. Is it possible to check it when the engine runs for only 4-5 secs...anyone have any suggestions or anything else I should consider??? thanks in advance.
