115 Worth Rebuilding?
Some people claim you need to back the timing off to less than the factory recommended 21 degrees and run high octane (92 or better) fuel to keep this sort of failure from happening, do you agree?
Replace all pistons, rings
and bearing as you have it torn down, so you might as well do it now.
Retarding the timing slightly is good as the fuels of 1978 are much
different than we have now. A little safety will go a long way.
