I would like to confirm our conversation on Friday last to the effect that since we have only .002 between an Aerolite piston being satisfactory and knocking after wear, if it is possible for us to reduce the limit on the piston from .001 to .0005 it is eminently desirable to do so. Will you please look into this matter, and let me have your views. BY/ BY | ||
