Blowing all that goo out will be good for the motor. Take spare spark plugs with you, though. Really. All that carbon and congealed fuel mixed together just shows how rich you were running those 2 cylinders.

If you can find a source for Quicksilver "Power Tune" in bulk liquid form, adding it at a rate of 50:1 to your portable fuel tank (add the right amount of 2 stroke oil, too) and running it for an hour or so will clean varnish and goo from the fuel pump and carbs, and loosen and blow out any carbon in your motor, too. Your motor will smoke more than usual while running it.

I used to have a local source for that stuff, but he went under in this economy.
