I have a 1977 Johnson 140 HP that just got new head gaskets. Cylinders are good and compression is 115 psi. With the plugs removed I get spark on all 4 coil leads, when i install the # 1 and # 3 plug there is no spark but #2 and # 4 still fire.
So far new starter, stator, timer base and power pack, swapped coils, new battery !
Any help would be appreciated. Thank you
