Default RE: JBA .56

Hi W8ye,Though SK crankcase has a manufacturing no (ie:KA 01569) at left lug,no signs on right lug.Crankcase carb base casting is square
not rounded and prop driver hub has no separate cone,only has a matching flat surface sliding onto crank.So Im not sure,same factory products with Towers.But carbs seem same factory production most likely.
