Kohler 18 hp Courage engine hard start valve issue and automatic compression release ACR This engine had the valve guide pop up on the exhaust valve, preventing the intake from having any vacuum to suck the air/fuel mixture in. I have also read it causes backfires but this one had hard cranking and no start condition after replacing starter and new battery. Thought it was coil but had strong spark
