With modern day 50 cc engines with electronic ignitions, if you need an external electric starter then you need to get your engine fixed.

Agreed. It is much easier to start a gas engine with electronic ignition than a much smaller glow engine. Just make sure you're following the recommended starting procedures for your engine....and make sure when you turn the ignition on and try to start the engine, it is never more than slightly off idle. I don't know anyone at the two fields I go to that uses an electic starter on a gas motor with electronic ignition.....
....but if you're set on getting a starter, I believe one of the most powerful options is a conversion called the "Persuader" for Sullivan starters made by Miller R/C. You can contact them at 707-833-5905. They evidentally don't have a Web site.
