Mustang 289
I recently bought a 68 Mustang for a project. The car runs pretty good with the original 289. I have replaced the points, condenser, coil, plugs, wires, cap, rotor, and the fuel pump. I have also rebuild the 2 barrell carb. Changed air filter and pcv valve. Now for the problem. When cold, the stang turns over a little longer than what I feel is normal but starts and runs fine. After driving and reaching normal operating temp, stang does not want to start very well at all. Sometime it seems like it will turn over for 30 seconds or so before it will start. I have been stranded for over an hour once before she would start. After she starts all is well again running good. Any suggestion and helpfull hints woul be appreciated.

One thing to check is the breaker plate in the distributor. Sometimes the pivot point gets loose and makes it hard to hold a steady dwell (and timing) setting. Does it make any difference if the vacuum advance is hooked up or not?
You might want to think about a Pertronix conversion. Eliminates the points and gives you a better spark.
Just my 2¢, others will be along soon.
EDIT
Or maybe not. I keep forgetting this is a "truck" forum and not just anything Ford. I'm kinda partial to the "classic" Mustangs too.

I havn't checked the breaker plate yet. thanks. If I disconnect thr timing advance, the car dies. I have tried to time it without the vacuum hoses hooked up but can't keep it running long enough. The plan is to put the electonic ignition in as you suggested. But not until complete teardawn and rebuild....Thanks Carker

If the dwell is changing that bad when you disconnect the advance, there's definitely problems in dizzy land. Also, you might want to try connecting the advance to ported vacuum instead of manifold vacuum. Or for a temporary fix until you get a "round tuit", leave the vacuum advance disconnected (and plugged), set the dwell that way and advance the timing a little. See if it will at least run and start consistantly.
