Is this the correct flywheel??

I'm hoping some ATCO / Suffolk experts can help to confirm something for me please. While rebuilding my ATCO standard / Suffolk Super Colt, which has the 75G14 Suffolk engine, I am wondering whether or not this is the correct flywheel for the engine/mower. 

The flywheel has the part number E9301 cast into it, has a plastic points cover with 'SET POINTS .018' on it, a removable magneto section held in with 2 cross head screws, and no other markings that I can see inside or out. No casting detailing the puller bolt spec i.e UNC which a lot of the older 75G14 engines seemed to use from what I can see. Here are some pictures

And the points with Coil/Condenser on the engine

I've dated the engine to 1979 based on the 'B' suffix before the engine number on the cast iron block if it helps.

Any answers much appreciated! Plenty other pics of the engine and mower restoration in my thread here: https://www.oldlawnmowerclub.co.uk/forum/history-and-technical/technical/first-ever-restoration-suffolk-super-colt-lots-questions

Yes, but you may just have rendered it useless by removing the magnet, hopefully not.

Thanks. Could you explain why removing the magnet may have rendered it useless please? I only took it off to search for any other identifying numbers so will kick myself if that's the case...

As far as I understand, the

As far as I understand, the flywheel internal was machined once it was in one piece, you may not get it back into exactly the right place. 

You seem to be going much further than I, or anyone else would do. You will probably end up with a machine that is much better than when it was manufactured. I much prefer them in their work clothes, or refurbished to as new. It doesn't help that what you see as vintage, I remember taking out of boxes and assembling from new ;-)

The removable section of the

The removable section of the flywheel with the magnetised sections can only fit back on exactly how it came off - thankfully. It locates on 2 spirols,(?) snaps into place and then the 2 cross head screws hold it tight. There is no movement in any direction once located correctly so I can't see there being an issue.
