I thought you already had that figured out Automan. Just wanted an excuse to put up a picture of a blown mini V-8 that´s all!
A ready kit? Haven´t seen any, not on rc or any other contraption that uses small two-strokes. But I can see no reason why a starter for a 50cc won´t work on a 26cc. Go pry one off a scooter moped at a junk yard or something...
I honestly think though that it would be better to make a homemade starter, it isn´t rocket science. There is anyway a bit of work fitting a gear to the Zen flywheel etc, so why not do the whole thing?
