hello shedpest, if you have a close look at the brochure supplied by deejay you will see the engine supplied on the mower was a villiers model 3G, not a villiers
midget mod. 2 or 3. The specs for the 3G engine are bore= 43mm, stroke =48mm, 70cc capacity and 0.55 HP at 3000 rpm. the midget engine has a 50mm stroke and bore, 98cc and 0.75 HP at 3000 rpm.the 3G has a 14mm spark plug and the midget an
18mm one.the points gap for both engines is 0.012 - 0.015". regards john
