I have heard only an etec mechanic can determine what the problem is. I have also heard that the spark can get pretty gummed up. They are a very fickle motor.

Thanks for the help guys....I fished a 3 hr tournament this evening on the river. I filled it up with 89 octane gas instead of the 87 and added a dose of injector cleaner. It ran really well and I picked up about 400-500 rpm. I did have trouble starting it a couple of times. If anyone else has any ideas please feel free to jump in.....

Watch the higher octane fuel............might burn HOTTER........may damage your power head.

Maybe run some Seafoam in the fuel and also spray it through the carbs while running!
