Hey guys I need some help! I have a OS 46 V ducted fan engine.
I removed the back plate for cleaning a while back and now its time for assembly. The only problem is I did not mark the position of the rear back plate. It is the older style I believe, the carb is mounted in the corner of the backplate. Anyway it can be mounted in four different positions and I know It only can go in one way because the rotor on the backplate engages into the crank shaft. Can anyone tell me the correct position for the backplate / rotor assembly?
Thanks a lot!
David
