i have a 1972 lawnboy 19" cut. d-600 engine, magnesium deck. very good condition. carb inspected and cleaned. reeds checked out ok. starts on first or second pull. everything works(on off switch, throttle control,primer, fuel valve). a few chips in the paint here and there but its 40 years old. could prob use a crank seal but its not too bad. no smoke running 32:1 quality oil.short on cash, not on mowers. i know people collect these and i have another one. any ideas what its worth? thanks jason
