How far exactly are you looking to go for (minibike) "original"?? You should get us pics of your motor maybe.. There are two different styles of flywheel with electric start... IF it's the aluminum flywheel.. you could MAYBE grind off the teeth of the ring gear, or unbolt them (depending on style) and THAT would allow you to ONLY buy a blower housing to make the front of the motor look rite... :shrug: But if ya have the iron flywheel.. You'll absolutely need a flywheel, AND blower housing, :shrug:
Then, theres a REALLY GOOD chance it has the wrong throttle setup.. SO.. you'll need that.... Then, for the blower housings to be (correct) is gonna need to be a small aluminum ID tag, rivited to the side of housing, with your serial and model numbers.... All of them after a certain time ( a long time ago) have just been numbers stamped rite into the steel cover.. The (aluminum tag) isn't THAT hard to find, but %90 of them (STILL AVAILABLE FOR SALE) in the world, are going to be some stupid gibberish numbers and say (Craftsman) on it, instead of (Model H35 xxxx)
SO....
blower housing + Id tag
cam + backing plate
air cleaner assembly
gas tank + mounts??
flywheel???
If you are sincerely looking to make it %100 1968 minibike correct H35, hell man, you might spend 100 bucks pretty damn fast on Evilbay..
I have all the parts ya need.. But I'm here to tell ya, they aren't free.. :laugh: Because ya need em to be (correct) and they are getting pretty hard to find here some 40 years later :hammer:
