Re: Just bought a Bikebug
I believe the outboard manual will get you close.
I would not buy a thing from that guy! He spammed me out big time when I was listing a bug on ebay! A buy in on a bicycle motor?!?
You have a Tanaka 23 cc engine I believe, you may contact the company and try to get some info.
I would look for a tank on ebay, but better luck just making a replacement.
You will have to re-build the carb I'm guessing and the one way valve can be repaired, replaced or substituted with various things, like a check ball of appropriate size.
