Repeating it doesn't make it true. 90 degrees isn't ever halfway down the cylinder.
You know what I mean. If the piston is 90 degrees from TDC its halfway through its travel of its stroke. At 90 degrees from TDC the piston should have gone the distance of the crank throw. At 180 it would have done a full stroke and be at the bottom. Dont you agree if the pistons travels 180 degrees it has traveled through its stroke from TDC to BDC ? Ron
doesn't work that way, punch in some numbers and see for yourself.
