When cold they will sound richer than when warmed up.

If this engine is set on TDC. Where is the magnet? Magnet should be passed the hall sensor in the direction which CCW.When viewed from the front it should be to the left of the sensor about 3/8 of a inch or 28 degrees.Just a SWAG.

Make sure the Ign box does not have a sticker on the back that says syncro spark or SS.They run kinda funny with both TCSA and SS.

I am measuring 5/8 inch from the center of the magnet to the center of the sensor with the piston at TDC. Dan.
