Ah, gotcha'. The problem is one cyl only, the others are fine on
bore size and make no noise. The slappy cylinder has good
compression, 155 psi, and it doesn't show any smoke or use oil. The
only problem, at the moment anyway, is the noise. Maybe it's only an
aesthetic thing, but it bugs me. Not enough however to justify a
rebore and new pistons (and while it's apart, mains and rods and
thrust washers, and might as well do a valve job, and while I'm at
it, how 'bout an Al head, etc.)
I digress. Here's what I think I'll try, tell me if it makes sense
to you. A 1" wide strip of .002" teflon tape on the thrust side of
the piston. Yes, I know that sounds goofy, but the adhesive, a
silicone, is oil proof and good for 400F; plus the teflon buttons.
I'm thinking about making the buttons, say 1" long, slip fit in the
pins, with a spring between then to keep them snug in the bores.
How goofy is that idea? Do you kow, offhand, the diameter of the
pin ID in a 1275?
