Pumping the pedal had no effect on s Stromberg carb. It doesn't have an acceleration pump to squirt extra fuel in by pumping.
The things that most likely cause that problem on a Viva are fuel evaporation in the pipes, rate but possible. A loose inlet manifold, there are just 3 bolts holding it on. An air leak in the intake system somewhere, check the servo pipe too. A faulty coil which is running hot, the insulation inside breaks down and shorts out the spark. As the coil cools the insulation behind to return.
