I put a thin bit of paper between points then feel for when points open by pulling gently on the paper, not 100% accurate but pretty close.

According to the book I have you should first set points gap 0.015″. Then set piston at 5/32″ before TDC, now align mark on flywheel with mark on backplate.
Whenever I time a Villiers engine I set piston to correct position then turn flywheel until points just start to open. I have never used the marks.
The tricky part is getting flywheel tight without disturbing timing.

You have a number of options, e bay, tractor magazines such as Tractor & Machinery or our own club magazine The Cultivator.

Pete, you need to resize the photo file as it is too large. See help and information section of forum for guide on how to do this.

I have just had a look through me copy and yes it does cover the 25A, B and C two stroke engines.

They are a fairly rare item so you may well need to wait some time before finding one.

The Acre is in 70 Years of Garden Machinery. Below is a copy of pages from British Tractors and Power Cultivators.

There is a guide to reducing file size for uploading photos in the help and information section of forum at https://vhgmc.co.uk/forums/topic/compressing-photo-files-using-ms-office-picture-manager/
The only way to test a magneto coil thoroughly is with a coil tester, a DVM will give an idea of resistance but will not be able to test insulation for breakdown under running conditions.
There is a good diagram of magneto circuit on a Villiers website

What engine is it? Villiers? Flywheel or other mag?

Photo did not upload, file size to large.

Looking good. The inside of the miller hood on my 56 is red.

Vic, the nut should go tight as it starts to pull the flywheel off the taper on the crankshaft, this is normal for Villiers engines. Just be careful it does not pull centre out of flywheel I had this happen once. The fun is getting it back, setting the timing and getting the nut tight again. Don’t be tempted to use fins to lock flywheel.
