Then the process starts all over again because the leak in the exhaust system is still fooling the WBOS, each time the engine is operated and then shut down, the new, richer self-learning table is added to the existing tune.

If it is dirty, that can cause poor engine performance or starting problems. Disconnected, dirty or fouled spark plugs are common causes for engines that won’t start. Spark plugs typically need to be replaced every season or 25 hours of use. You should also check that the spark plug gap is set properly.
