I have a Manco Dingo. It has the larger oversize tires. It either had a 5 hp or an 8 hp. From what's left of the motor it looks like a 5.
It needs one front rim (cracked) and one rear rim is bent. 1/2 the motor is on it. Didn't come with the other half. Would make a good project.
I also have 3 front rims/tires from an '84 Honda ATC 250R 3 wheeler I'll throw in with it and some spindles and disk brake rotors from the same.
$125 if gone by this weekend.
