Here are some clearer photos.

I was expecting someone to just say "Yeah, its a ......" - I don't feel quite as stupid now.

CobbaDog - those "pipes" are in fact wires. The one on the left loops over and is then earthed to the cowl. The one on the right is just a frayed end, I'm not sure where that is supposed to go yet.

To me it appears to be an oil pump. Black cap for filling oil and 2 pipes on top each side line in n out. Need a pic that is not as blurry to help a bit more. Only problem with my idea of it being a pump, what would it supply the oil to?

Thank you to both of you. I have not noticed any screws on the sides but I am a 'blindman' by trade. Will have a real good look next time I can get out to the shed.

A lighting coil, perhaps?
If you could get it running you may be able to measure some output from it.

Hello Polybus,
I have had lots of Villiers motors, still have a few and like you I have never seen this fitted to a Villiers.
Hopefully someone will come up with an explanation.
I am most interested to find out.
Cheers Grasshopper Max

Cobba,

Ian is onto it - just put a dial indicator on it to see how much it has moved - it doesn?t take much to move .1mm (Which is .2mm on the Diameter !!!)

You tube is your friend !!!! Have a look

I just bought another lathe - from memory it?s 10HP, 2m between centres and can spin 660mm in the gap,
When I worked at the engineering works I probably spent over 1000 hours standing in front of it !!! Could fill a wheel barrow with little chips before smoko !!! Loved rough peeling off the metal. Will have it home soon.

Cheers Justin.

My expensive Chines lathe you can adjust the tail stock
undo the screw on one side a very very small amount and tighten up the other side

At the risk of displaying my own ignorance.....what is this??

I know the engine is a Villiers Mk 20 (a very rough Villiers Mk 20), but what is the gizmo on the right hand side of the engine (as seen in the photos), under the exhaust (no not the carburettor), the other gizmo.

I have a few other Villiers, another Mk20,  a 425H, a bunch of 10s, 12s but none of them have this gadget.

I have looked at heaps of Villiers online, but again, can't find any with this gadget.

Its got some wires coming out of it, so (guessing....)magneto?? instead of the flywheel magneto?  The dial on top completes about 3/4 of a turn - have no idea what that does either.

Can anyone tell me what it is?

Thanks heaps.

Thanks for doing so Rudy, it is just my pea brain not engaging as to what is happening and how it works.

WOW, talk about perfect timing on this topic.
I started making some new valve guides and what I did was to stick the round rod of cast iron into the chuck (3 jaw only) and centre drilled the end so that a live centre would fit into the centre hole.
Next I made a couple of very light skims across the length of the rod, about 200mm as the rest was in the jaws.
Once I had a constant cutting action across the rod I then took out the digital calipers I have and made some measurements. From the chuck to the tailstock it reduced in diameter of 0.14mm.
I noticed that you suggested to adjust the tailstock. This is the part that I do not know how to do or if it is possible to do on my genuine Chinese made lathe.
Yes, there is always a catch isn't there?    :o
