quote Chris_P:

I would first ensure it is a lean sneeze, and not an ignition miss. I like to use inline neon spark testers for this to watch quality of spark while running, and see if flutters in the tester corresponds to the miss or sneeze.

If indeed spark stay strong throughout the run, I would look for the air leak.

Start at conector. Fuel lines. Crankcase. Possibly crank seals?

First though I would try new plugs before anything major.

I only have an open air tester. Spark is white, not blue. Almost seemed a little weak. I did notice a crack in the bottom coil.
