Stuart & Aaron,
Thanks for your suggestions.
I certainly didn't check the 'pistol' for straightness while the PTO was
disassembled, but there is no eccentricity evident when the tuning knob
is rotated.
I like the idea of "wavy" washers - I'll probably try that out when I do
the next rebuild.
I guess much of the problem stems from manufacturing tolerances. The PTO
which is slightly "stiff" using 3 washers felt "loose" with 2 washers
before its rebuild - presumably that must be due to differing tolerances
on the replacement parts, or perhaps wear on the old parts.
Then again, perhaps I'm being too "picky". It didn't seem like a problem
until all three could be compared alongside one another :)
Thanks again for your help,
Steve G3TXQ
