Woodruff firmly in place.The supplied lock nuts are useless,as you say,as there are only two or three threads on the internal coned outer nut.I,m using a substantial ring spanner on SC nuts but am not accustomed to having to use so much force-feels excessive and brutal.I like the idea of lowering compression,the comp on this engine is massive.A bit like trying to flick start a BSA Gold Star! I would not dream of hand starting this one.

Thanks very much for the response boys,some good and sound advice.To clarify my question,I,m using 5% with half and half synthetic/castor and OS F plug (new) Plug running from a separate batt via usual mosfet panel.16圆 Master broad blade.
