Not sure what I'm doing wrong here. Using an electric starter (Dynatron on 24 volts), I can't keep it on the spinner! The starter spins a rev or two and then gets thrown off, like it gets out of balance. Last time, it got thrown off and ended up in the prop, breaking the prop. I'm guessing that you have to have the starter lined up with the spinner better, but I didn't think I was that far off. Any hints on how to keep this from happening? 12 volts isn't enough power to start my big engine, so I can't lower the voltage.
