Actual tooth count will vary with the rock of reciprocating mass at actual stop. Hypothetical? the last guy got it right...4cyl IL=2 etc. [Reply]  [No Email]

Would it be safe to assume that a four cylinder would stop in two places, a six in three, and an eight in four? This is a question, not an answer. . . [Reply]  [No Email]

And I have heard it said that most engines stop in one spot, but have never researched it. Maybe there is an engineer or physics professor lurking out there somewhere who will be able to enlighten us. [Reply]  [No Email]
