It looks a little gummy on the butter flies 365mag. Should I put fuel additive or spray carb cleaner? Runs fine just wanting to stay ahead of it. This is the 5th season I've had the boat and never done anything to the carb.

Carb cleaner.

Try this......

This stuff works awesome!!!

Parts stores carry it?

Some should, but I usually just order online.

You can get in there with a toothbrush and clean those plates & bores up nicely- just hose them down with Gumout & brush away.

Just don't tell your wife you used hers.
