Mitch, yes after repeating the measurement a few time I got something on the
order of +/- 2 degrees and was similarly surprised. I sent out a similar post
to the list, I think the response was not to worry but I forget the rationale
as to why, perhaps because it was a small percentage change in timing. But in
any case, in my case I decided to bias the sprocket to get the cam center lobe
closer to 110 degrees. I dont recall if the bolts were special.

I am trying to degree in a cam and noticed the cam gear has enough play
in the bolt holes to move 3degs in either direction. Is this normal. The
bolts seem to be standard without a larger than normal shoulder. This
may be built in to the gear to fine tune because both sets of holes are
the same.
