Does anyone know if the bore is the same for the EBay Chinese “80cc” A & B engines? I think I might have damaged my piston...
My rod says FM80. I damaged the jug though, so I’ve been using a spare jug I had laying around. But that one came off a motor with a ZL rod.
I ended up using my damaged jug though (small corner piece broke off -who cares lol) but now I’m getting this ringing noise from the head.
Sounds like an empty spray paint can.
Theory: ? Bore is smaller on the ZL rod & I ended up shimming my piston down???
Idk what’s going on but it does not sound right.
Are all the wrist pins the same?
