There should be two timing marks on your pulley. The mark closest to the
engine crankcase is a sharp cut V. On the same pulley, the second mark is a
small dimple about 7 mm to the left on the further edge of the pulley. I
believe (if memory serves me correct) that the V is 5 degrees ATDC and the
dimple is TDC. You can verify just by rotating the engine and seeing which
mark comes first.
To adjust the timing, disconnect the idle stabilizer and set the idle speed
to 850. Using your timing light, rotate the distributor until the V lines
up with the center split in the crankcase.
I noticed an interesting thing with my engine. On the oil flap door (where
the license plate is), there is a sticker that says the correct idle speed
is 750 and the timing is not-adjustable? But since I have a DH engine, I
followed the recommendations in the Bentley. Anyone else have a similar
sticker?
By the way, this week I pulled my engine to do a rebuild. How hard was it
to do a rebuild? Where did you buy your parts? Did you rebuild the
crankcase?
