Gasoline engine starters.
RORO
Yup, as I pointed out a Dynatron starter (by Sullivan) with a Miller Reduction Unit on it should start just about anything up to 150cc. And as omawho pointed out at 24V you should be able to start 200cc and above. This combination makes a very powerful starter. I would have to venture a guess here and say it's got more guts than the Megatron. One thing for sure is, it's a lot less clumsy than the Megatron.
Also as I pointed out the Dynatron by itself will start engines up to 2.4 CI and many 3.5 CI engines. With the Miller Reduction, you've got a powerhouse. (5.8 - 6 CI)
To answer your question, yes, go with the Dynatron.
Cost? A lot less than a lost finger or thumb.....
PS...I guess I got everyone with the age thing, too bad it's true. :cry:
