My FA91S made about the same power on CDI compared to GI when timing was 28* BTDC. It responde very well & increased RPM up to 35* BTDC & remained the same @ 37* BTDC so I backed of to 35*.
It is at 34 degrees....
Did not see too much difference in operating temperature between 28 and 34 degrees.
Need to improve cooling.
