    Piston and Piston Pin assembly
    Part # 718-1193 A2 for KE7, KF7 and KG7 per parts manual
    Unless previously rebuilt it is likely the upper and lowerr crankshaft seals are crap,
    Reed failure suggests rust or
    too long service.
    KE7 powerhead sits disassembled on my bench, I know ALL about getting one apart and am about to learn how to reassemble. First time
    is the charm or the curse
    Parts Manual for KE7, KF7 and KG7 series is essential unless
    you know them well enough to work on them blindfolded,
    Almost anyway,
    Good Luck
