Hi Gizmo,

Yes it is a bit confusing LOL

I looked on the English Villiers site www.villiersparts.co.uk that you mentioned and clicked on HELP and you

get all the pictures of the engine models

and they have a picture of the engine that we are talking about and it is called a Villiers Midget Mk1 79cc 2 stroke

and then the 98cc is called the mk2 and mk3 barrel numbers B6698

Check this pic http://www.villiersparts.co.uk/3838.jpg

OMG now I'm starting to confuse myself LOL

Cheers Ken
