If the car runs fine from a solenoid jump then it sounds like it might be a switch issue. Does your key return to the run position after you crank the car, if its hanging up in the start position then its going to leave the starter running. As stated before I would make sure the ignition switch is wired properly, then I would make sure the switch itself is working properly, I've replaced two in my car and every parts car I have has broken switches. They don't hold up well. you can always bypass the switch and jump the wires and see if it cranks normally then, if so the switch is your culpret
1966 Mustang - Engine Won't Start
Hi,
I own a 66 Mustang, I6 auto C-4.
I recently replaced the alternator, ignition switch, starter, and starter solenoid. Everytime I try and start the car, the starter motor stays stuck to the point where it sounds like the car is at full throttle without even depressing the accelerator.
I disconnected the throttle linkage and even bypassed the solenoid with a screwdriver, but the starter still stays stuck(the speed at which it's turning sounds like the engine at full throttle). I had a mechanic show me this trick and he was able to get it started a while back, however recently the car either cranks aimlessly or the starter catches, there's no in between.
Took the starter to get checked and it passed. I'm completely out of ideas and paranoid about turning the car on given the fact how many times the damn starter has stayed stuck.
Any help would be appreciated. At the end of my wits here. The car has been sitting for six months

Yes, in theory. Carbs are funny, one clogged port in there could cause it to not function as intended, so if the gasket were covering a port of some kind then it would cause problems. thing is, you don't know what the guy before you fiddled with. Your settings could be off, your carb could be dirty, you might have gaskets on in the wrong place. the simple things are the easiest to start with but If you have never fooled with carb adjustments before you should read up on it. It could be that the idle set screw is just to fast, but carbs are not a one screw fixes all. Find out what carb you have and google adjustments on it. A good deep cleaning of your carb might be necessary
