Terry,
After doing steps 4 and 5 the "V" notch didn't align with the indent on the
cam thrust plate.
The v notch is at approximately 10:00 and the number on the sprocket where
the cam dowel is located is 3 (as the indent is sort of midway between 2 and
3 I have assumed that 3 is the number required as 2 would mean that the cam
lobes will no longer be facing upwards). Where do I go from here?
