Yahama Jog part question

[omgwtfbyobbq]

Does anyone here know where I would look for parts for an 80s Yamaha Jog? I believe I need an automatic choke, since the currently, it won't start when it's less than ~90 degrees outside w/o some starting fluid. I figure the wax has expanded too much. I figure if I can't find anything I may be able to rig up a manual choke, but either way I'm hoping someone has some info!
