I have a 2002 Johnson 150.. Had issue with rough idle and wouldn't run smooth etc. In checking for spark the Port bank has no spark.. Checking the manual for test. Temp is warmed up as required (150 +) , but still no spark.. The CDI troubleshooting sheet says to unhook black and yellow wires (plug).. Did so and spark came back.. Have not found cause yet.. Is there an issue if we leave Quick Start unhooked? Seems to start ok without it..
