    I am guessing it must because it dramatically affects the way spark plugs color.

    Hey Red,
    There are some cheaper alternatives. They're cheapos, but they get the job done. Us 2 stroke guys with perfectly vertical cylinders can get away with just a piston wash light.
    Anywho, I keep one of these in my bag of goodies at all times. Like I said, it's a cheapo, but it's good enough for me!!!

    Crazy, that's a great link. I may have to pay them a visit. I'm in there town 4 times a week! Any idea what pricing is like? Maybe a forum discount?

    I've got the PV100 now, works good, but I have this one on the way also.
    This is the cheapest price I've found.

    so the less carbon build up, the richer the ski is running. The more carbon build up, the leaner the ski is running?

    Correct. As an example, picture 1 would be richer than picture 2.

    Man, do I feel fucking stupid as shit right now. Maybe that will explain some of my problems from back in the day. I got to say, you guys opened my eyes up on this one. I was thinking completely the opposite for some reason. Phew, now to go look at the pistons on my xpl and see if I can lean her out or riching it up. Thanks guys.
    Now heres another question, say you've been running on the edge lean, if you richen it up, say after an hour you look at the piston top again, you think some of that wash will have taken off the carbon build up on the piston or will it still be carbed up like it was prior before?

    Excellent question Shooter...and the answer is...maybe.

    So take a picture of the before, and then take a picture of the after.

    You should see a washing of a lean piston, for sure ON TOP OF THE PATTERN. After a while it will stabilize into ONE pattern.

    Not sure how many gallons of gas it would take to carbonize a piston, if you are just taking small changes to go leaner...
