Wie Gehts! Can't help you with the manual, but I owned two of these motors some years
ago. Great stuff. Kinda big and heavy for their displacement, but certainly no worse than
some of the bricks they're selling today.

Functionally, the motor isn't unique. It starts, runs, and adjusts just like any other ringed
r/c engine. The HB carb looks like a perry and adjusts the same as well.

Any good fuel with 5-15% nitro and a good oil package would be fine. Omega comes to mind with maybe
an extra ounce of castor tossed in for good measure.

10-6 / 11-6 props are fine, but the final choice is going to be dictated by the type of plane you
install the motor in.

These were really top quality motors, so you shouldn't have to rely much on luck, but...

Good luck with it!
