      I get the new condensor and points in. The points contact area are much larger than original which I guess is a good thing.

      My question is why was I sent a capsule with what looks like grease and a piece of polishing paper?

        The grease would be to put a little bit on the points cam.
        Not sure about the paper……. maybe to polish the points?

        Prepare to be boarded!

          I figured it out once I posted that and then found out the new spark plug I bought is crap compared to the 30 yr plug that came with it. Going to clean up threads and install here shortly and let er rip.

            I have searched around. Do y’all know what the correct plug is?

              Bright blue spark, trying priming with anything under the sun that burns and still nothing. It’s spitting out a lot of black from exhaust since I have the lower unit pulled off.

              About to throw this thing across the yard.

                Without me re-reading the previous five pages of threads, what does your compression gauge read when testing this motor?

                  It was 90 the first time I checked. Now it’s at 80-84

                    Going to have to rethread spark plug hole and put a insert in it. Then recheck

                      My book says a McCulloch 4 takes a Champion J18Y which appears to cross reference to NGK BP4 or 2911.

                        The champion and the Ngk plugs are different for sure. Champion looks closer to the old plug that came off of it. Funny thing is that the original plug, "ac" brand, still fires bright blue
