[TR] Weird A** Question

[Wbeech]

Lacquer thinner should clean everything up very well. You can let stand
overnight in the piston well to unstick them from the cylinder walls.  Rings
should be OK, just be sure of the clearances and that the tracks are clean.
Would probably hit the cylinder wall with a hone lightly just be sure all is
smooth and ready to go.

I was able to source a NOS set of AE 86 MM pistons and liners from our friend
Mike Bonaducci in Vermont (802 439 5815).  He has one of those huge old New
England barns full of unobtanium Triumph parts he's collected over 30 years.

One such part were those pistons and liners that were brand new, packed in
cosmoline...in 1972!  Heck, I still had a year left in my navy enlistment back
then!

Question 1:  what's the best way to clean off old rock hard cosmoline.

Question 2:  the pistons have been inside the sleeves all this time.  What are
the chances that, despite cosmoline, they've rust welded to the cylindar
walls?

Question 3:  would rings that have been depressed in a cylinder for 42 years
have lost their spring and should I replace the rings as a matter of course?

Mike has guaranteed them, so if there's a problem, he'll take them back.  But
I'm so curious about this, I thought I'd take a stab anyway.  Plus the price
was right.
