Dan, on one of the rare occasions when I actually read instructions, I
had my crank cut to 2.500". Before I reassembled the engine I learned
about the leaking seal problem, so shortened the spring (per Jack's
guidance) to 8.25". I didn't trim the seal split ends, but will this
winter when the engine comes out again. Damn damn damn. This time I'll
shorten the spring to 8.0 and trim the split per Tony's guidance.
