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
