I would still try shimming it out with a couple of washers. I had a ford starter that would travel too far and lock itself to the ring gear destroying the bendix when it did. it took about five replacements ( under warranty) before the store figured out that the rebuilder was leaving out a washer at the front of the shaft that limited the amount of travel for the gear.
My job is to do everything nobody else felt like doing today

On my Detriot motors if it's been -10 or colder & batteries are low, I've had the starter stick on. I'll shut battery master switch off & back on again & most times it stops it from turning. But if I leave it on to long i'll have to tap on the solenoid to get the contact apart. Mine are Delco solenoids which I've taken apart & took emery cloth to get a better contact till I can get a new one. That's what I meant when I said"wielded together",the inner contacts get hot & stick together. If it's that cold I'll put jumpers on while I'm heating the motor to avoid starting sticking problems. And I do keep two good 1000cca batteries in each machine. But most times if it's that cold I'll wait till warms up a little to avoid other cold weather hazard's

Hello,
 If the solenoid is part of the starter then there is a pull in winding and a hold in winding. Once the starter starts ( pull In) then the hold in winding takes less amps and will lock in if the flywheel ring gear is worn or maybe if the spring is incorrect on the solenoid.

hope this helps.

Did you ever get this sorted out?

I just went through this on a 79 f600. Put in a new solenoid. Turned out i over tightened the posts. So when I hooked up the battery the the starter would turn the motor over. Super scary when the truck tried to take off with me under the hood.
 The over tight posts got welded together with the current and created a continuous path for power to the starter. A new solenoid solved the problem...
Good luck

And do disconnect the battery when under the hood. I've even hit it with the oil filter wrench on the ranger.

the delco starters with the mounted solenoid are different then starters with remote solenoids. The large wire is hot and runs the motor. The larger wire to the small stud comes from the ignition switch (or from a separate relay or solenoid used as a relay) The smaller wire from the other stud is the ignition bypass. When you turn the switch 12V  energizes the magnet and pulls the lever that engages the drive to the flywheel. When it gets to the bottom of it's travel it closes the contacts and powers the starter motor. It also supplies 12V up the smaller wire to the coil to provide hotter spark for starting. Points can only use 6 volts and use a resistor coil or a ballast resistor when in the run position.
So if the drive gear sticks into the flywheel ring gear the starter will continue to run until the battery goes dead.
Most likely a different starter will solve it. The nose has a bushing that can be bad or the is a stop ring on the shaft that may be missing . Other wise first inspect the flywheel ring gear for burrs. Usually you can just file them off. Next install the starer without the solenoid and engage it manually to see if the gears engage without binding. You can use a wire feeler gauge to check the clearance. You can't shim a international starter like a GM it mounts differently. I have never seen the spring have anything to do with it. The rpm of the running engine throws the drive back,the spring just keeps it there.
