    Opinions on piston wash

    Can I have your opinions on piston wash as per the pics.

    The carbon build up is from 30 hours running.

    Cheers

    Cheers Guys, wanted second opinions.

    Also found this thread that explains it and what to look for.

    You can see there is a very large amount of clean piston showing from all the transfer port areas on top of the piston. This is from the cool overly rich air/fuel mixture washing the top of the piston clean. Note: this is when you sled runs like crap. Ideally, you should have about a fingernail size portion of clean piston around each transfer port as shown in the next picture.


    It's been running OK so will lean it down just a bit as gas is cheaper than a rebuild.

    Personally, I think Pistonwash is a closet homo. But hey, what do I know?
