Front plate installed. The brown you see is the color of the lube I am using - parts are clean. Note the three and nine oclock holes - you can see the edges of the counter balance through them. It is in the WRONG place for timing. You want them so that a line through the timing reduction gear bearing through the drive shaft is at right angles to the edges of the counter balance. The drive shaft needs to rotate about 45 degrees clockwise to be right.


Here is the addition of the REDUCTION GEAR (47062700). Note the easy to see timing mark on the lower gear, and the really hard to find mark on the drive shaft. This is a photo through a magnifier.
