Hi Guys,

Well its turned out to be an unsatisfactory spark issue as I couldn't get a visible spark from the lead across the gap to the plug using chicken pliers. This was achieved using a second operator to crank the engine over at a rapid rate. The following pictures are the donor part to replace the culprit and the donor engine prior to total strip down. The donor engine is a C12A-01-01 and has nothing more than worn rings but an absolute lovely bore and no issues crank or bearing issues at all.

Now I've read quite a bit about the timing issues and the correct placement of the Ignition assembly when putting a Villiers back together again. Is there any workshop manual for the 412 Engine or similar in the manuals database ? as I'd like to read all about it before pulling the 412 apart and doing the substitution.

Anyway here are some photos of the Ignition assembly and the engine after the initial removal and basic external componentry, such as Cowling, Carby, Exhaust etc.

I will say that I would like to obtain another Ignition assembly to replace the one I've taken from this engine as its in just to good a condition to scrap and with the rings replaced and the bore lightly honed / valves refaced it will be a great substitute for the 412 should it go bang at some later stage. Honestly these little Villiers are a pretty well built long engine from a mechanics point of view.

Cheers,
BB
