I have the motor to my 100 re-assembled and after messing with the timing a
little it started last night.
The good news oil pressure came up pretty quickly and nothing is leaking.
However, there is a loud high pitched squeal when the motor is running so I
haven't done the 20 minute run in recommended for the cam.
My guess and hope is that is a vacuum leak, but I am not sure.
I eliminated to the possibility of water pump or generator by taking off the
belt and starting it up.
I have tightened to vacuum line, intake/exhaust manifold and carbs themselves
no difference whatsoever.
It does not make the noise when turning over with the starter, only when
running, I have not tested the effect of increasing revs because I am being
cautious.
I am hoping itis a vacuum leak, but am afraid it may be mechanical/internal.
I know that is not much to go on, but any advice or educated guesses would be
appreciated.
Also thanks to the list for helping me to get this far.
