 Is there a universally excepted method by which to  adjust the  valves =
for A  TR three? I know when I asked about this  before that Randall =
sent me a link to a bunch of articles but I don=E2=80=99t think any of =
them  concern setting The valves.  Where can I learn to do this?

Thanks, Paul Dorsey TR three 1960
