10 H. P. Johnson Q D 15 had no spark. Put new condensers, points (set to .020) had coils checked by dealer was o. k. Get spark on both plugs but only will jump gap on spark tester set at about .060. motor will not start. Is this spark o k ? If not what is wrong? It poped once. Could coils be weak but still test o k. Thanks for any help.
