Ignition coils for 1603

Hello all,

I recently noticed some hard start/long cranking issues with my 1603, and found I have a very weak spark. I replaced the plugs and wires last year, which helped with this issue quite a bit, but I did not get around to refreshing the rest of the ignition, which is my plan for this winter. I would like to go ahead and replace the coils now however.

Does anyone know of good replacement ignition coils for a driver, or specs for the original ignition coils?

Thanks!
