Hello,  It feels like I have spent my life working on my first cylinder
music box over the last month, but I have hit a problem.  I am having
difficulty in getting my governor assembly to run freely and would be
very happy if someone could help me after reading the following.

Before anything was done, the fan would kick in on moving the start
lever; the endless and gears of the assembly including the gear on the
end of the cylinder were already greased.

On disassembly I scribed the position of the adjustable lower pivot
of the endless.  Everything has been cleaned, a new ruby fitted as the
original was cracked, the top pivot of the endless polished with a nice
dome to it; the endless has about 0.75 mm of travel between pivots,
light grease applied to endless, and set up back to scribe mark.  There
doesn't look to be any wear in the pivots of first and second gear in
the assembly.

Should applying force to the first gear by hand be able to lift the
play from endless and rotate it whilst holding the assembly?  I can't
get this to happen, but I can flick the fan itself quite freely which
will spin the first gear.

Should the teeth of the first wheel be off centre to the vertical of
the endless?  Mine is slightly to the left.

I have put a little grease on the second cog as well to see if this
helps and because of gear noise, I have not put any on the pinion of
the second wheel so as to not transfer to the gear of the cylinder like
it was originally although I still have some gear noise which there
wasn't originally; am I correct?

All is free without the governor assembly in place and there is no drag
from any stop work, and the best I have achieved is I can get it to
start with a flick.

What sort of tension should be on the spring before the Geneva stops
you, and can too much power be an issue for the governor?  Although my
problem remains the same regardless of any amount of power.

I have not done anything with the teeth of first cog or of the worm of
the endless.  I feel I'm close to the finish line with this project and
have put everything into it, but I would appreciate any advice.

Thanks,
