where can i find an electric starter that will start 130cc and up motors

There are several large starters available on EBay. However, I have seen more accidents while using an electric starter on large engines than I have hand starting. I’ve honestly never had one that wouldn’t hand start ( 40cc to 170cc ) easily. If I had one that wasn’t running in 10 flips it usually had an issue with fuel delivery or power to the ignition.
