    Piston wash pictures...have a look

    Take a look and tell me what you think.

    Started running 32:1 working my way up to 40:1. I was at the lake for 4 days and I really don't know the actual screw setting I'm at now but they're at least 1 turn out from stock settings, may be more...I'll verify the setting tomorrow. Would .50mm over & Pro series reeds need rejetting?

    My camera sucks so plug pix don't come out so good. All three are dark on the intake side and lighter colored on the exhaust side. I see a faint ring after plug chops but to be honest the plugs aren't really "telling" me anything.

    The domes have me puzzled too. The pto is clean but the other two are dark at the top with a little dry soot right where the dome starts to go up....between 9 and 11 o'clock in the pictures

    I LOVE your center cylinder, very safe for rec riding and extra loads.
    PTO is a little lean for rec riding but would be great with a little race fuel.
    MAG is even leaner yet.
    If it were my boat I'd bump the PTO 1/2 jet size and the MAG would receive a full jet size. These are of course IF all your needles are adjusted the same amount of turns.

    I found the pictures but no thread. I figured when I had time I'd hunt it down again or repost it.
