Andy,
Yes I do have a dial gauge but after thinking about it a bit more since my post
yesterday, it occurred to me that if everything was perfect, then #1 & #2 valves
should be fully closed and register .010, for perfect timing for #1 piston,
which
they currently do.
I'm now suspicious that you're right as well as Michael Porter which suggested
that my old chain may have been so sloppy, and/or off a bit (I cannot remember
now
after 18 months) that the punch mark I added to the cam sprocket may have been
off
as well.
Perhaps some others might agree/disagree with this logic.
Thanks for the help.
