A real simple conversion mate. I took the ignition off of it and opened the mixture screws about half a turn extra. Added a glow plug adapter and a OS number 3 plug and away we go. 80% methanol and 20% cool power blue synthetic oil and she runs great. i know of another one thats been in service for quite a while in an extra 300 and its a powerhouse. Mine is going into a 1/3 Christen eagle (in a couple of days actually) and will be about twice what it requires. Turning a 22x8 at over 7K and developing an estimated 5 HP. I'll have some better figures when I get some gear together to record some parameters and results.
Cheers, Wiz.
