I had a nice used one but sold it last year to a needy person.

If you get inspired by Surpass II parts, it wil require:

The head - The valves, springs, etc are the same
intake manifold
carb
backplate

The Surpass II is about 300 rpm faster than a Surpass I or a Magnum

The secret is the glow plug is recessed down into the Surpass II head about two milimeters
