Oxford Allen scythe – maybe Villiers MK25c ??

[vhgmcbuddy]

Hi Agaim !!

Well … looking properly at the two sets of points I’m giessimg the insulated washed is the one missing under the adjustment crew on picture 13
I do have it under the nut (usually screw) in photo 12

Made out of the same brown material as the large circular section !!

And then a huge thank you for the obvious gap !!
My father gave me a feeler Guate from another mower which he said should be about right ! This maybe the thing they was throwing me off.

Picture of feeler Gauge attached.

I’ve now haves that gap and I HAVE A SPARK 😊😋

I’ll now go and see if it’ll start !!

Half way there 😊

Thanks again

As I know have a spark…..I haven’t checked the insulator bush under the points ? not sure if I should take it apart to check….

I’ve put the piston at TDC as is when the notch on the shaft is at 12pm

I then screwed gently the cover on which has what looks like a factory arrow marking on and I have lined that up with the mark on the backplate which is at 10 0’Clock.

There is another homemade marking at 11 0′ Clock ?? I’ve left that for now…

Once I’ve got it to finger tight without moving the shaft Ive held the cover marking tight with the 10 0’Clock makings together and tightened up the main bolt…

now as per some online instructions for starting Mk24/25c ….

Ive done as follows…..

taken out of gear by un-engaging the lever on right hand handle .
I’ve turned ON the fuel tap
Primed the carburettor until fuel spills out at the base of the bleed nipple
Closed the air filter slider ( which I previously cleaned in fuel)
Given it 1/3rd throttle

And when I pulled it on a few occasions I get a backfire and nothing else…

At least that’s something I guess !!

Sorry to be a continuous pain !! but Any thoughts …..

Kind Regards,

Mark

Your points gap should be between 12 and 15 thou.
Do you have access to a vernier gauge , if so , remove spark plug , and reset timing so that your points just begin to crack open at 3/16″ before top dead centre, without Mr Googles help I’ve forgot what 3/16 equates to on a vernier. ALWAYS re-check after you’ve fully tightened the flywheel.

All I can say is listen to the wise man Andy Frost !
Thank you soooo much for all your help , teaching and expertise .
It’s made my day and I will look at all sorts of things with a villiers engine from now on 😁

It runs and stops like a beauty and ticks over really nicely .

Does seem to leak fuel when idle from the bottom of air filter ?

I’ll check the float . Or just it off !!

Thanks again ….

Next to test the 110v generator that goes on the back 😊

Glad to hear you’ve cracked it , it’s just what this forum is for……helping one another.
I always time Villiers engines with a Vernier , the marks were stamped on at the factory when new in pairs , after 70 odd years very few are totally original , with the Vernier method you are eliminating any doubt.
Keep enjoying it and above all else stay safe.

Andy.

To move onto your generator, it looks like a Tuscan, 110 volt DC which were used with Tarpen accessories – a nice new avenue of collecting, there are plenty of 110 volt Tarpen hedgetrimmers out there, also chainsaws, mowers and even little tillers! It also doesn’t matter if they are AC or DC, as the brush type motors that Tarpen used will run on either!

3/16″ = 0.1875″ or 4.76 mm
