One thing I ran into on mine was the needles.I went and bought new needles right off the bat. They were the rubber tipped kind. They poured fuel constantly. So I dug my old solid metal tipped needles out of the trash and reused them. If you have any of the metal tipped needles,put some tooth paste on them and ''lap'' them into the seats like you would when lapping valves. Nearly 7,000 miles later and never a fuel leak.

On the backfiring thru the carbs. I cant explain this,but on some older carbureted engines they will tend to spit back thru the carbs when you go to start them. It seems that would only happen if combustion is reversing,like you explained,but sometimes when they lean out while starting that can happen. A good working choke and a correct idle mixture setting can cure this. IF that is even your problem

Don't you just love ''mystery'' bikes? Good luck bud!
