Polini 40cc Air Cooled 4.2 Rebuild Package (new type engine)(Sandy Spec)

This package is for the newer 4.2/6.2 air cooled engine that uses the blue teflon crank seals - generally identified by the cylinder kit 323A however it is possible to fit this cylinder to an earlier engine - if unsure remove clutch to see if the crank seal behind is blue rubber.

Sandy Spec - is the preffered main bearing for Sandy Mcintosh
