RE: us41 in byron p51
I have enjoyed both of mine. One has always started just fine with the spring starter. The other was converted to electronic (CH) when the magnet mounting boss broke off the front of the case (no crash involved). It starts beautifully by hand. The only difference between the two, to me, is weight. Some of my installations need the nose weight. They will get the spring started magneto version. If I need to save weight at the front, it gets the electronic version. I think it is about a 10 oz. difference.
ANY time I have tried to hand start the magneto ignited engine it has been no-go. I am not in this hobby to fight my engines. If it ain't easy, I do sumptin diffurnt.
