It is very difficult to estimate a value especially when machine is a non runner. Have you had a look at e bay to see what similar machines make on there, this is a good guide. Note photo file is too large and needs reducing to 3072KB or less, there is a guide on how to do this in the help and information section of the forum.

It looks like an Auto Culto, club member Jim Beacon is the expert on these. He has a facebook page at https://www.facebook.com/autoculto/ with loads of photos and information.

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.

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?
