RE: Engine trouble
It took a long time for me to finally get past the (looking for the word ????????) oh yeah, lack of safety thought, and bought a starter about 4 years ago. Before that I was a hand propper, or should I say a thumb smacker, finger cutter (those Master Airscrew and APC props are sharp) tenis elbow try for ever on a really cold morning to get the engine to start guy. Then A friend said "hey try this thing" man what was I thinking. All of my broke in engines will had start easily, but think of this one really important issue here PERSONAL SAFETY.
I have a starter I would give you also, that is if it is an issure of cost.
By the way. If you get a field box with battery and panel so you have power for your starter and the all important CORDED GLOW DRIVER. You can never know when that cordless driver you are using will go t/u and leave you stranded or having to borrow one. Some redundant systems are worth the effort. Or you can go arround like some guys I see with half a dozen battery powered drivers floating in the top of their box and searching for one that might have enough juice to start them.......]
PERSONAL SAFETY. If I remember correctly AMA had a report on prop related injuries at one time.
I can think of a half dozen prop stikes this summer I saw while out at the field.
