Ryk's coils and plug wires installed. Started engine, running on one cylinder right off the bat. Left cylinder intermittently fired, but the coughing severely. Inspecting underneath carbs in the sunlight showed a healthy spray of gas coming from left carb/cylinder mating surface when cylinder coughed...Not sure if this is the cause, or effect. Engine will not start at all now. Both cylinders showing healthy spark with strobe gun while it WAS running. Ordering $32 worth of O-rings now..probably another 2 weeks...what a PITA.
