If it’s not one thing…it’s another….Sort of a long read…but here goes.
I have a 1966 Mustang Convertible Inline 6. Great car lots of fun, but of course the usual constant tinkering…
Recently car has been hesitating and performing poorly. Odd since it had a new Holley remanufactured carb and used to run great. I think the timing mark on the dampner may have shifted. As I check that religiously when it acts up. I would set it at 10 to 12 degrees BTDC. In any case, I got a new autolite 1100 from Pony Carbs. Nice people, real helpful. Actually called with a question and spoke to Jon Enyeart the owner. Definitely knowledgeable with regard to Mustang engines.
So I changed out the carb, reset the timing the way he recommends which is turn thr distributor counter clockwise until it pings under load, then retard a “smidgen†until the pinging no longer occurs under heavy load. Car now runs and accelerates great. Like a new car. But (always a but), almost as the last bolt goes in…the starter starts to act up. Story of my life…so I check the battery and starter solenoid and they’re both okay. It is the starter I’m sure. Take it to local parts store, put it on their bench and it is bad.
Now the strange part…I had the clutch replaced in May. After the replacement the car had a minor vibration at around 1500 rpm. Was not there before the replacement of the clutch. Was not the transmission as it would correspond to engine rev with the clutch down. So I suspect the guy who did the work may have not properly balanced the flywheel when he reworked it. Odd as all he works on are Mustangs. He says “ hey I can’t chase down every vibration…I’d never get any work done.†Last time he’ll see my wallet. (Pony Express in Beltsville MD)
So I pull the starter…and see wear marks on the starter housing that would indicate the flywheel (or some part of it) may have been rubbing up against it (more like gouging it out). When I put the new carb on, the vibrations pretty much went away, so I had suspected maybe one cylinder was running lean or not getting enough fuel/air, etc from the bad carb…so now confused as to what caused the vibration. Will be replacing the starter tomorrow. Could the gouge marks have been from a worn clutch?
The link below is the starter and opening into the bell housing showing the flywheel. I can’t see any places that could have caused the wear that I’m seeing on the starter housing. I looked at the service manual and I don’t see anything that would stick out on the front side of the flywheel that could cause those huge wear marks in the housing….

Anyone have any ideas???
