    Just got parts back from Mr. Viper!
    Super excited to get it back together.
    Big thanks to Don for getting this done, even though he has been super busy with work.
    Appreciate it greatly!

    Well, had a chance to get motor put back together and in sled.


    Also had a buddy wrap my headlight with a new product he got called headlight tint.
    Much better and more even that the spray stuff.

    Will re fit pipes, then mark and remove for EGT bungs to be welded on.
    These CPR pipes are tough to find room for that as they twist around each other so much.

    And I see you replaced your 20cc dome head with a stock 700 head to! Smart move.

    What are the stock dome cc anyway?

    OK, update:

    Motor is repaired and back in the sled.
    EGT gauges installed.
    PTO Cylinder is runing about 200 degrees cooler than Center and Mag.
    Thought it might be the gauge or the probe, swapped them both with Mag, Same thing.
    So, took carbs off, needles are correct, but had 60 pilots in it, were supposed to be 50. So fixed that.
    Think I have eliminated carbs as the cause.
    I now have a stock head on it ( Got off Ebay) Head had been hot, as paint was discolored, with a single layer head gasket.
    Im wondering if I dont have a slightly warped head, allowing coolant in the cylinder.
    I really see no signs that is happening, but I did pressure test the coolant system, and
    found that it slowly leaks pressure out. I dont know if this system should hold pressure.
    Also dont know that my tester is getting a good seal either..

    Any thoughts ?

    Found this on PTO side
    Looks like a leak, but doesn't feel damaged.

    Place a straight edge or a machinist scale over that portion of the head or jug..... whatever that side of the gasket was facing. See is any feeler gauges can slip between the two which would indicate a deviation.
