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..
indeed i watch the video davidsstuff boom out came a rod..i will definitely not be over reving for sure..
Well i guess i cant send pics just yet..but have me saito fg33r3 running much better today..cleaned carb last night made a mod to the manifold 3 brass tubes!! It is reliable on idle much better a little smoother through the range..
Thanks for the tip on personal operation failure 😁
