NAA Starter

I haven't worked on the Jubilee for quite some time.
Last summer after paint put most of the external parts back on. All wired up, installed battery and pushed start button and it cranked over as it should.
Prior to that I had made a straight hand crank, just a pinned shaft and a pipe wrench to turn it over while I primed the oil pump.
Today made the rest of the hand crank with a handle and while cranking it over by hand I heard a strange springy sound. Finally put my hand on the starter and it was turning.

Maybe that's the way it's supposed to be, but I don't know. I was surprised it was turning while I was hand cranking.

Tried pulling it back out and discovered I'd need to pull oil filter which I don't want to do.

The pinion was about 1/2" away from the body of the starter. Watched a few Youtubes and their starter teeth were in the same place on the shaft.

The starter teeth can't possibly be engaged all the time ?

Sorry for the length of post. I'm just wondering how it's supposed to work. As I said it cranked OK with the battery.

Way back 10 years ago when I pulled all apart I did what folks warned against and turned the ratchet.

It took awhile but I got it reset properly before installing it.
I'm guessing the pinion is engaged when stopped ? Owners manual says it Releases when engine starts.

Your thoughts appreciated.

The starter drive engages when you crank the engine with the starter.

When the engine starts and ''overspeeds'' the starter drive it retracts.

It doesn't re-engage 'til you crank the engine again.

But I'm thinking the engine didn't start between the initial cranking with the starter and you cranking it manually, so it would be expected that the starter drive would be engaged.
 
Thanks Wore Out & da bees.
Parts manual shows the drive as 1cm-11350-c. Apparently it was common for many vehicles in the 50s. I think mine may be OEM with the coil spring on the end. Electrical is 6V Pos. ground.
As I mentioned I was just trying to understand how it functions.

And da bees, sadly I am often times mistaken hence my enquiring to you all with greater knowledge so I don't remain mistaken !
