Sounds like you bought a 48cc cylinder for a 66cc engine?
You need the right parts...

yes, without a pic, I'm guessing you got a 49cc head, but it may be the strange version of 80cc that uses 6mm studs

either way, it is easiest to get the right one - the 49cc can not be made to fit, but the 6mm 80cc might be made to fit with a lot of effort
 
There are some 6mm studded 80ccs

If you look up cylinder studs they say 6mm 49cc and for all others run 8mm. There is not any one that makes a 80cc even thaw they call them that the biggest is only 69. something CC. Has anyone else seen 6mm studs on anything bigger then 49cc? Now I think and not sure there might be some a LITTLE bigger maybe correct me if I am wrong but nothing with 47mm bore with 6mm.

I've seen 6mm studs on 66cc engines. it's mostly older ones that stay overseas, as far as I know all the ones that make it to the states have 8mm studs
 
Yep boy go fast still sells 66cc 6mm top ends oops. prob. need the 8mm.
