Alex,

Congrats on your find and successful delivery.

I will say, for the record, if you have the S7 FFW for a Rotax, that is great. Some of my friends with the S5 and old "dynafocal" engine mount system used at the time of the S5 leaves a bit to be desired - those had to have the intake manifolds reversed port to starboard which places the carbs so far away from the engine centerline that vibration and consequent fuel leakage as well as the carb popping off the socket were not unheard of.

Best to you and keep us old timers on the list informed of your progress.
