Some Viulliers piston ring sets unearthed recently.

Found these amongst my Aspera etc. stash, I wonder how I might track down the engine they fit.

A tad too small for A tad too small for my lightweight Villiers engine.

I was using Firefox when I made this post, I used it to replace Google chrome when my computer was playing up and found that I was no longer able to type out comments underneath the pictures, maybe I will use Chrome in future to log on here.

Not all providers are the same, if that's the correct term.

Thanks for replying wristpin, but the engine I've shown with one top ring sat in is the one you advised me was 'probably' a 125 or 150cc lightweight, if it is in fact, then the roughly 50 thous end gap means my bore is shot!

I must find a parts book for that engine soon.

Don't know if it has any meaning, but there is a label that says A15 on the 4th photo. The A15 was a 146cc engine

As the box says A15 on the side that seems likely . According to the book by Jack Sizer the A15 was 65 mm std bore, whereas the MK 15  was 63mm and F15 64mm. E & OE
