I have a us 41 engine with electronic ignition on a one third scale cub. I have three different heavy duty starters an none of them will turn it over enough to statr it. I have two other gas motors a 35 and a 41 with spring starters which i like very much. no hassle no worry just pull the prop back and let it go. I was wondering if it would make sense to put a spring starter on this engine I do not like flip starting a 20 inch prop.I am not concerned about the little weight the spring will add. I was wondering if the guys at the field would look at me a little funny. p.s. i dont like flipping a gas prop. any thoughts on this will be appreciated. Thank you
