I looked here http://www.searspartsdirect.com but sears shows the coil group is NLA. It does have points so you could change it over to a 12 volt system. I need a piston and man they like it. ($143.00)
I know this is a old post. But I have three of the HH120 if anyone needs a semi complete engine minus carb and igition drive pulley still attached. and some sheet metal parts for the SS12 and Suburban, let me know. :flag-airforce:
