I think that you have a vacuum leak. Check to see if the vacumm advance on the side of the dist is holding vacuum. The rubber diaphram in it may be ruptured. This will give you a vacuum leak as well as affect the timing advance. On some of the Ford sixes, all of the timing advance is controled by vacuum, there is no centrifical advance. That's where I'd start looking.

Make sure that the vac. hoses are good and the carb is not leaking at the base. If the vacuum line to the vac. advance is metal tubing, make sure that it's not kinked. This will stop or reduce the amount of vac. to the advance.

I'm assuming that the clutch is properly adjusted.

I also have a "66 I-6, but it has an auto tranny and I'm having the exact same problem. After rebuilding the carb, I got a good strong idle on it but it always stall out when I put it in drive. If I'm lucky enough to get it on the road, it stalls whenever I slow down to make a turn. I know it's not leaking from under the carb and I can't find any other leaks. Will I have to replace the distributor or can I just replace it piecemeal? I'm new at the mechanics, but I'm picking it up fast. Any help would be appreciated.

Happiness is...putting the top down and putting it in the wind.

You might have a C4 auto, and those I know have a vacuum sensor to determine shift points. If that sensor is ruptured, it could very well be enough to stall the motor. But also, try revving it in park or neutral. If it feels like there is a flat spot, there's most likely a vacuum leak anywhere in your vacuum system (power brakes, transmission, ignition). All the rubber hoses and possibly ignition can be checked by spraying them with starter fluid. It should rev up a little bit when you spray them.

I mentioned the distributor vacuum advance canister. Did you check it? If it doesn't hold vacuum it's going to stall. You will not get any timing advance. Just exactly what do you mean that you checked the vacuum? How exactly did you do that?

just do this, take the breather off the carb, cuff it with your hands, and try to stop any air from getting into the carb, and if the motor doesnt start to die out, then you have a vaccuum leak. if not, then i'd say you have a fuel problem.

vacuum check

I visual checked the pcv valve line and the metal tubing from the vacuum advance there didnt appear to be any kinks in the lne. This may not be the correct way to check , but I unscrewed the vacuum advance line on the carb side, ckeaned it and sucked back on it. the disc in the distributer turned and as I held my tongue over the opening creating a vacuum the disk slowely turned back. does this mean the diaphram is bad. or was that test just a waste of my tme. thanks

stumped

Ok, so I replaced the vacuum advance, and the advance line to carb. I figured why the heck not it was only 14 bucks. And …. Still nothing she stalls out as soon as she is put under load, I can’t even get the clutch all the way out. She just bogs down and stalls. She idles great and revs up nice without any pings,. I am stumped. Any ideas? thanks

Could be the coil? On mine when the coil started going out it would idle and rev fine, but when dropped into gear it would die.

The diaphram was bad. The disc inside the dist. should stay in position as long as you have vacuum to it. This wasn't a waste of time, you found a defect on an important component on the performance of the engine, even if it didn't solve the problem. At least it wasn't expensive.

It's a shame that you find diagnosis of engine problems as being a waste of time. Don't you enjoy working on your Mustang?

You never did specify trans as std of auto. If auto, check the rubber line at the passenger's side of the trans that connects the steel vacuum line from the engine to the vacuum sensing valve on the transmission. Even if it appears okay, the rubber line will swell and soften over time and allow a vacuum leak. Easy and cheap to check.
Best,
Al
