Troubleshooting a Two-Stroke Outboard Engine, Part 2

Yesterday, we left off with checking and fixing ignition wiring. Once you’re confident that there are no lingering wiring problems, turn the engine on and listen for the engine turning over, and failing that, clicking. Turn off the engine and locate the starter mechanism or solenoid if there isn’t an engine starter.

Tap the starter or solenoid with a screwdriver handle, and then try the ignition again. Next, pull the spark plug cap off and use a socket wrench to pull out the spark plug. If the spark plug is covered in gunk, replace the old spark plug, and add in new synthetic 2 stroke outboard oil. Finally check the fuel tank, vent, and fuel line for leaks.
