SO I HAVE AN 89 5.0 THAT EVERY TIME ITS COLD AT START UP IT JUST DIES OUT. IN ORDER TO KEEP IT RUNNING I HAVE TO GIVE GAS FOR ABOUT 2 TO 3 MINUTES.AFTER IT HAS REACHED NORMAL RUNNING TEMPATURES IT RUNS FINE. HERE IS A PROBLEM I FOUND BUT DONT IF ITS RELATED TO THE PROBLEM.ADJUSTABLE FUEL REGULATOR IS LEAKING.JUST DID TUNE UP SPARKS PLUGS, WIRES, CAP N ROTOR. AND I ACTUALLY REDID THE TIMING JUST IN CASE.mY BUDDY ACTUALLY CLEANED OUT MY THROTTLE AND ADJUSTED MY IDLE. ENGINE IDLES EVEN BETTER NOW BUT THE PROBLEM STILL EXISTS.

ANY HELP IS APPRECIATED IN ADVANCE.

I fixed this problem on my other notch, the same night I crashed it. Set timing, by doing top dead center, (basically restabbing the dizzy at TDC). If that doesn't work try replacing the dizzy with a known good one, because I did replace mine that same night. The old one had a lot of play in the shaft.
