    Are you following the other K-45 post? The compression lever opens an exhaust valve to relieve cranking pressure on one (starboard) cylinder. It also closes the intake port so you crank the motor on one cylinder making it easier to pull over. Personally, I don’t use the compression release on my PR, PO, S-45 and V-45. I find them easy to pull over.
