i have 2 Villiers brochures May 1957 and September 1960 , both feature a 2T (249 twin ) engine , and by 1960 the 324 3T. The two engines are different regarding cowling , fan and which side the starter motor .
Question are there other differences , are they interchangeable , why the changes , where they available at the same time and finally which type do people have in their Scootacars ? and are these original ?
also does the 3T engine look the same as the 1960 2T ? - i assume so
