I have a 1980 40 HP 2 cylinder moter. Two days ago moter ran fine. went out yesterday filled gas tank with some 92 octain the same as befor. Now the moter basicaly boggs down at about half throttle, but runs and drives. At 3/4 throttle it will either die or rev up, then rev down, then rev up again and so on. At full throttle it revs up then dies. what may be going on? Thanks for any info Bryan
