It is here, under a pile of other treasures, somewhere.  Anyway, they talked about matching the cylinders on each bank to scavenge, put in short baffles that led into a cone shaped collector that narrowed into the exhaust pipe.

I am trying to find out where each of the cylinders are, in their four stroke cycle, when cylinder #1 is at its Power stroke.  What am I doing wrong??  Where is cylinder #6, in its stroke cycle, when cylinder #1 is on the power stroke?


you forgot the 90^ offste in the crank
