When to power tune?

[Perfidiajoe]

I have always power tuned my engines in the spring, after I burned out my winterized gas. I would fill w/ fresh gas, take the boat for a ride,& then power tune the engine. When I got back to the dock, I would change the plugs, fuel filter & water seperator. I know some guys do it before winter lay up, I just figure it is better to get all the gook out early in the season, & not let it get on new plugs. Which way do you guys think is better, & why? Thanks, Joe

Re: When to power tune?

Start of the season sounds best to me, as you say, to remove the winter "gook".
