      most likely the condensers.

        I’m gunna order the ignition kit from the link that was posted above ..
        I just took the coils out .. The resistance on the the primary jumped around but both coils settled in on .4 ohms …
        The secondary I didn’t get a reading on either one . OL was the reading if I did it right …

          Nice Engine. Just research the data plate.

          beautiful!

            Depending on your meter “OL” could mean overload or open line. Check at your highest resistance setting first, then drop down to the next lower setting. Like Dave say’s bad caps too. Primary winding should have very low resistance, secondary should be around 4K or so. Bad plug wires or connectors? No telling who has added their “Handi-work” to the mix!!
            Don’t assume these parts are good. I have found new electrical parts that were BAD too.

              where did you mesure the secondaries… at the end of the plug wire on on the screw pin inside the coils coils should read 4-7 kohms

                how to test coils…

                http://www.pochefamily.org/outboard/Coils.htm

                as to testing condensers well that is not very practical since you can’t simulate real operating conditions but….

                should should not see a short…

                . and a good old analog needle meter can give you a clue.

                black test wire to casing red to wire should give you a momentary swing to short or low resistance… then the needle (ohms) should raise to infinity as the condenser charges up with the internal sensing battery from your meter.

                modern electronic meters don’t give much of a visual while they sample the resistance build up.

                again not a proof but that is what you should see on condensers .

                  Yes that is where I tested . I didn’t get any reading just OL .. I have both a digital an an analog meter.

                    well…if your testing is accurate that would indicate 2 open coils which coincides with the outcome (no sparks)

                    chineese coils are cheap and have worked fine for me …… if you are not in a hurry the ones with free shipping area good deal

                    they don’T come with the little rubber boots on the coil/wire junction so just install the old ones ( I also add dielectric grease inside under the boots)

                        Back on it a little .. Hard to find time ..
                        I guess where I checked the secondary on the coils beforeI was not getting good contact on the pin inside. So rechecked and one coil was 3900 ohms and the other was 7100 ohms ..
                        So checked the plug wires . Top one zeroed 0.0 out and the bottom one I could not get reading OL .. Is there a standard plug wire set I can get with the plug boot molded in or will I need to make my own ..
                        I picked up the points and condenser set . I checked the condensers with an analog meter the old and new . They all read the same for the most part . The needle would jump then ease back to infinity.. If that sounds right ..
