Ignition Timing, 210cc Longstroke Tamini

I have a simple question, but hard for me to find a clear answer.


I have:

Malossi 210cc cilinder 


Longstroke Tameni crankshaft (45021000)


Sip cilinderhead for long stroke (the red one)


What should my ignition timing be?


I can't keep it running, the woodrufkey just snaps in half
