I have a serial number of 3457775 from Rotax made in Austria - Is this a snow mobile engine ? It was clearly advertised and shown in a trike - just interested in rebuilding a single carb 503 but have no history on this engine.
3 4 5 7 7 7 5 is the serial number - any help ?
2 x 72mm 61mm 496.7cc 503 - any leads or info would be appreciated
