Re: decarb question
The only way to really de-carb a 2-stroke outboard is via complete teardown and cleaning the ringlands on the pistons--nothing I've ever seen in a can does more than remove some carbon from the exhaust cover--which doesn't hurt you anyway--best thing is to use a supreme grade synthetic oil and not put the carbon in there. A 2 year old loop charged motor (yours) is in no danger from carbon build up, wasting your money.
