I am waiting on the ignition system now..and i probably should get looking for a suitable magnet before the mail arrives..im now wondering what carburettor i should use..i have a saito fg21 and the carburettor fits on the ft160 manifold good.slight mod would have it mounted..i used this carb on the asp fs120 and ran perfectly....
you guys are doing some brilliant work on these engines
Just a tip about the FT160 in general: Do NOT overrev it. The engine is rated for 9K but that number is pretty optimistic. Andrew White from JustEngines fame once advised me to make ABSOLUTELY sure to keep RPM below 8500 under any circumstances including flight. So prop it for around 7500~7700 (peaked) on the ground, and tune it 500 RPM rich to compensate for unloading. Is valid for the OS 160 twin just as well, since these engines basically share conrods.
Gassers handle a bit of lugging down WAY better than glow engines, in fact, they prefer it even, so that is not a problem at all..
