VS57 Parts Interchange

This ongoing section provides a parts interchange for the VS57 variants and the Avanti SN unit. Hopefully, given time, and information (anyone got any?) the SN series will be covered as well. It also provides a useful cross-reference of McCulloch part numbers versus Studebaker part numbers.

Many thanks to Mike Mudd for the Studebaker information.

The item numbers refer to this commonly available VS57S schematic diagram.
