    This shouldn't be a problem if at least one plug is removed from each cylinder. The prop can be
    easily moved with one finger if all of the top spark plugs are removed for compression checks

    Here's a pic of the engine compartment my 1943 Willys Jeep MB. The anti chafing material can be
    seen at the bottom of the photo, just above the grille. As jimrice suggests, it is thinner in
    the middle...

    Looks like two different valves, one earlier, and one later, same part number.

    These are Univair's part B57-239, which look considerably different than those in post 504, but
    much the same as those in my post #517 above: Look at Univair's diagram above. It shows what
    KAP bough...

    KAP, Here are the bleeder valves I think you actually need, for use with the 10034 lines shown
    in your drawing above. They are the later design found in the L-4H & J. They mount horizontally
    and are b...

    Imagine a world where Germany and Great Britain reach an armistice and peace agreement in late
    1940. The extremely effective British naval blockade of occupied Europe is lifted, and Germany
    is able to...

    I think all Cubs have a wormhole inside the brake system. Fluid goes in and comes out in
    another universe, never to be seen again. I swear I've pumped a quart of hydraulic fluid into
    the brakes over t...

    Only full proof way is to drip the total wing after complete assembly. Most aircraft
    manufactures did this. I don't think Piper did this with wood spar J-3s. Instead, it looks
    like the wings were bui...

    Post #29Stan J. Miley wrote several superb research papers on engine cooling. They are worth a

    Or just tighten the prop bolt on the forward blade first, if we're talking wooden prop. I relax
    the prop bolts for twenty four hours at each annual, per Sensenich recommendation. Then, I
    slightly snug...
