Bought KE7 and same White Merc for $50 each. KE77 was junk ,but, it had race prop, Removed flywheel from White Merc, coils, points looked like new, At a swap meet a member with experience and tools took it off my hands for $50 even before I could tell him the coils looked great. Most do not like to take on PIA projects ,but, some like them.
For me No Profit, No Loss and lessons learned,
