Well ... to make some correction , the sound is 'click' ...click when you turn the engine main shaft !

Ok . for the HS needle 2turn open , regulator have not touch it , original setting , prop APC 17X12n , fuel cool power 25% .

Yes , when the engine run it does have white smoke , ... and then engine won't idle low ........

Any need to retune the reg ?? Or after broke in ??
