Condition is EVERYTHING.
Location is important as well. Selling a motor in the American market from Australia, will affect the value.
Also, does it run, shift, pump water as it should? Is a fuel tank included? Is it complete?
These questions mean the difference from a $50 motor, ( parts motor), to potentially $500 motor is fully restored cosmetically as well as mechanical restoration.
Add to that, its value IS, the amount you are willing to sell it for and they buyer is willing to pay.
Name your price, if no interest, lower it until someone enquires….
Ignitions are the buggar on these, great motors but coils are getting harder to come by.
I know this does not help, but you hopefully may better understand, why it is so hard to put a price on a motor that is almost completely unknown.
