      I have a 571.11 and need a spark plug for it. Anybody know the modern replacement?
      Also need the teardrop shaped shaft tube if anyone has a good one.
      Thanx.

        Was a C-7, now is a Champion 516 plug. Gap is 0.025, points are 0.020".

          The number 7 Champion is now 516, the C-7 is a higher running temperature plug. It is now 526 and hard to find. Of course these are just recommended starting points. My advice – run what ever works. . . 😎
