Concerning Dual ignition: I also get 100 rpm more with both ignitions on. The base for starting my 1835 VW is a 4016 magneto that has very low time and is very clean inside. After starting I click on the great plains electronic that is fixed advance. I converted the magneto with a very nice harness kit that uses 8.5mm auto leads by MSD. This kit is by G3i and has very good step by step instructions that allow automotive spark plugs to be used.
