Re: raw 80cc- Project: Gunnabe
Hardware kit is for headbolts, manifold bolts, and frame mount bolts mainly. Everything else is fine.
Gaskets - i like to stand by that if you break the seal on a gasket, replace it before you close it up. Black RTV rocks for adding some extra sealing power on paper gaskets.
Idle Screw - get a new one. The screw that's stock has no threads on the tip, and is rounded so as to not get flakes of metal from the slide in the barrel/jets.
