RE: Leak/Stall
Great, looking forward to your advice Mindcrime. I've had similar issues.
I think the front bearing leaks a bit as per common Toki hi crank pressure, and my crank had a 0.8mm thrust play when new, so I dismantled the clutch assy. and put a shim between the front bearing and the brass collet. This has minimised the leak and reduced the crankshaft play to normal. The problem before was the brass collet is about the same diameter as the front bearing inner hole dia. so the collet can be "pushed in" thru the bearing inner hole.
Mindcrime, can you also pls avice if a (slightly) long reach plug eg: Sirio S6 is compatible. Or can you advice which OS plug (I have many) is best for 20% nitro 12% oil 22 degrees C.
Thanks,
