Max I have a hard time remembering what happened last week...
Yes that's the problem when it's a while ago ,I don't think I've used a Villiers 4 stroke since the eighties.
Thanks Speedy for that info. ,I've now looked at a few old Villiers 4 stroke motors, the 12 A motor , the Mark 10 and Mark 12 and they also
have a tapered crankshaft but haven't seen exactly the same flywheel as at the start of this thread but looks like it should fit.
Cheers
Max.
