Never use starter fluid to start and outboard, they drain all the oil lube from the internals.

I wasn’t using it to start the engine, I was spraying it around the carburetor while the engine was running to check for a carb vacuum leak. Thanks.

Spraying around the motor while running is how they sometimes check for vacuum leaks on a 4 cycle motor. What happens is when there is a leak it sucks the fluid into the motor and it will rev higher….that means you may not be spraying it directly into the motor, but if it gets in there, it can still cause damage. Make sense?

We just know from experience that one should never use that stuff on a 2 stroke..
