Morning All, I've been having problems undoing the flywheel nut. The nut is too tight to undo it with a 15" adjustable and stuffing the bore with string.

I'm also trying heating the nut up and using a impact gut with no success so far.

Any Ideas would be much appropriated, Thanks

Never had a Villiers flywheel nut stick but try to work against the inertia of the flywheel (say with the correct 'hammertight' spanner) rather than wedging piston.

Note that once it does shift, it will go tight again after a few turns as it also acts to pull the flywheel off its taper.

Not tried it with a Villiers yet, but I've locked a few motorcycle cranks by putting wood blocks between the piston skirt and the crankcase mouth to stop it turning then used an impact gun on the nut.
Just a thought, it is a conventional thread and you're not trying to tighten it?

On something as small as the Mar-Vil, I think you'd have an evens chance of breaking the big end cap doing that.

'Almost' certain its right handed - will check at lunch time!

The correct flywheel spanner will do the job without jamming anything up and risking damage.

I've still got one of those which I've had since my days at Warsops on the 1960's.

The slogging spanner was not available for long, the one I linked to was what Villiers issued in the 60's onwards.

Also fitted the spark plug.
