It was around the time i first got the boat and i figured it was dirty carbs. It wasn't. Then i played with the main jets, It had hydro tec heads on it and i got some extra jets with the boat so i figured maybe it had never been jetted properly. Then it slowly went rich again so i took the prime start unit apart to see if it could be it. |
