Best way to clean out carb and gas tank.
Let's think about this.
We all know gas and water don't mix. And soap will normally leave some residue behind.
Always use fresh fuel.
As for the carbs. If you are just wanting to clean them out then spray carb cleaner in the jets and other
openings. This includes taken off the bowl. It is easy and don't let it imtimidate you. Don't adjust any
of the mixture screws, needle/clip settings, or jets if everything is running ok.
I just did this last night to clear up a sputtering issue I had on my Kodiak. Took about an hour to strip off
all the plastic and get it buttoned up again. Now she runs like new again.
