I had the same car years ago, '65 Mustang, 200 ci 6 cyl. Was a three speed, converted it to an automatic, did a pretty extensive restoration on it. I thought I would share my story about it in the hope it helps. I replaced fuel pumps, did distributor work, made sure the vacuum advance was working. Replaced the carb with a full rebuilt one from a company that specialized in them. Tuned that little car using timing light and vaccum gauge and got it running about as good as any other car on the road. No matter what, it still had an issue with rough running and stalling, when hot. One night I came home from a cruise, parked it in the garage, went inside for a while. About an hour later, I go back in the garage and notice the smell of gas. I take off the air cleaner and look down the carb and see a very slight drip of gas rising out of the air tube, dripping down on the throttle plate. So I finally determined the following. This engine, while being generally dependable, and fun to work on, features a carb spacer that has a passage running through it that the heater hoses are attached through. This was FORD's attempt to provide heat for the carb in colder weather helping it to come off of choke faster. I am in Florida, and that feature is usually not necessary here, and the fact that there is that spacer between the carb and the intake just begs to cause issues, IMO. I found out that the heat from the heater hoses cause the fuel in the bowl of the carb to expand when hot, causing a slightly flooded condition. It was like the car had a chronic case of carburetor post nasal drip. I sold the car and moved to another project just short of me running those heater hoses in a different way so they did not heat up that spacer causing the flooded condition. I imagine that when these were new, that spacer may have not caused many problems. About 60 years later, those aluminum and pot metal pieces are getting tough to deal with. Also, we should not assume that any new service part we get for these things are not messed up right out of the box. If you watch Uncle Tony's Garage here on YT, you will know he has been reporting for a while now on how QC on new car parts is pretty much out the window. When you think that these cars were built to last just a few years, and that we can still keep them alive at all after 50 or 60 years, is really something. Anyway, I hope my story helps you into getting to the bottom of this. All the best, and thanks for the videos.
That does make a lot of sense. I believe you were onto something there. The issue stopped last fall and hasn't been a problem this spring. I'll be curious to see what happens during the upcoming hot summer days. I really appreciate the detailed response. Thanks for your time!
We have all limped cars back home more than once. Sounds like wheelbearing time I have had more fords (9" style bolt on bearings) loose axles than GM C-clips. Very pretty area as well. Nice and green compared to our brown and dead everything and no mountains. Congrats on getting it back home and inspected.
My 66 coupe is in major repair mode right now. Im going over every system to be as sure as possible to eliminate problems doen the road. Got spare everything I think, love these old Mustangs! Shes a driver. No show queens here…
Replace your carburator to intake manifold gasket That can cause stalling too id also look for vacuum leaks maybe bad vacuum lines or those vacuum blockoffs cap things
Now that the car goes down the road, mostly, it’s time to focus on critical systems. Fuel and electricity. Also I love the steel wheels, especially they were wider.
Would love to see the full unedited video with all the stall outs and restarts. Also would be cool to see cold starts of everything carbureted you have from inside showing what you do with the gas pedal and whatnot
Man what fun would have it been if it went easy and without any worry??? It did just fine. Yeah you may have a wheel bearing issue cropping up back there. Overall though, drive pretty nice? Where ever you live is some pretty country with LOTS of open running space to really stretch a car's legs out. Here in the concrete jungle, we just test out brakes and cooling systems, constantly in traffic. It gets old! Great Video Andrew! Seem like carb issues asise you are enjoying it! I switched my car that i know will sit for more than 6 mos over to clear gas (ethanol free) ever since, haven't had ANY issued with them since, if i let them sit.

Nice! Show queens are nice but they’re not for me. The driving is one of the best parts!
Thank you Mr. Boom Lift, I needed to practice for parades. JUST NOT TODAY!!!
Hahaha. True.
Every classic car owner knows your struggles with the support car in toe! Catching all green lights!
Haha. That’s the best comment I’ve had in awhile. 🤘
Great video, The driving videos are very satisfying for some reason lol I know you were frustrated though. 😎✌️

I know autos have the dash pot adjustment mine is a manual so not sure how to check

If you can't get the carb to work properly let me know, I am pretty sure I have one that is ready to go.
Thanks Bill! I’ll let you know.
Choke issue?
Where in PA are you located?
Hey Jeff, I’m in Milroy. 👍
