I just purchased a Kolb Twinstar mk 2 with a zero time 503. Would you be able to tell me how old the motor is? Serial number is 3609552

3609552 was produced 22-May-1986
( no further information is found in the factory database)

I was able to confirm (through the North American distributor's paper archives) that this 503 engine was originally sold by the ROTAX dealer LEAF ( https://www.leadingedgeairfoils.com/ ) in July 1986... perhaps you can contact them for more information (bit of a long shot, I know...) :whistle:
