The spacer you have is for the 24 volt coaxial starter. For the starter in the photo you would need the thinner spacer. At a guess I would say it is around 1/2 inch thick.

24v ... I was trying 12v on the original.

Know a part number of the spacer I should be looking for?

Just a stupid yet obvious question. Have you tried your local starter/alternator rewinder? There may not be one in your area but here luckily there are still a couple of old school shops capable of rewinding a starter. May be worth pulling out the phone book and seeing if you have a local rewind shop. Even if worst case they can't fix it maybe point you in the right direction.

It's not the winding that is a problem ... I think the magnetic field has degraded ... the gear is half way out and does not retract from the flywheel.

The starter had probably been overheated and collapsed the power in the alinco magnet.

2 options in my book, re-instate the magnetic field as you would re-charge a magneto or take you spacer to a machine shop and have it milled down to size.

well,

Gary sent me a spacer along with a rocker push rod .. the spacer does not fit my housing -- just slightly bigger. The spacer fits the starter nicely ...

I took the original starter to a shop  -- the owner is 85yrs old and recognized the numbers as a starter from a boat. I'm like, yea .,.. that's a big possibility.
So he said he will return it look and operating like new -- good to me !!!

Honestly, i don't like not having sources for wear parts ... i have no idea how long ago this starter failed -- or why. I hope i can source a spacer for this china clone ...

Looking at the manual you provided, I was reminded of a boat I used to have circa 1973.
It had an SR2 rated at 12BHP continuous. On the side of the fuel control was a stop with a lead seal. Breaking the seal allowed the operator to advance the throttle to "WAR EMERGENCY POWER" I never tried that, but the engine could produce that 12 HP effortlessly. The heated air could be ducted to the cockpit and sure kept it warm.

Nice bit of info there Hugh, It is amazing what can be found out on these Forums.

Will try to load another 2 manuals but one in each post in case it over loads the system

Sorry the last one I have was titled A25 Lister Air Cooled but must be too large a file.

Apparently Spitfires had a seal like that too.  Break the seal for emergency HP.  Hence the saying "through the wire"  If the plane came home with the wire broken, the engine had to stripped and rebuilt, which apparently pissed off the techies.

Even more great information. Some Techies are just like big sheilas and whinging about anything that makes them do something for a change.
