Hi Guys and a very merry Christmas to everyone! As the subject says, I face a huge problem. On Saturday a brand new six cylinder Jabiru motor was delivered to me for installation in a customers Whisper motor glider. Do you think he would tell the difference if I installed my 3100 corvair instead and kept the Jab for myself. Seriously guys this motor is truly a thing of beauty. It came with a beautiful Airmaster full feathering prop as well. One thing that confuses me is that the manual says that it has a transistorised ignition but to me it looks like all it has is a dual magneto ignition (lawnmower style) with each firing 3 times per revolution and the spark sent to the correct cylinder by the appropriate distributor. I must admit that I havn't even removed the motor from it's crate yet so I might be missing something. The wiring diagram even shows the way to switch the ignition off is to ground the coil. It looks like a lawnmower ignition, it acts like a lawnmower ignition, therefore I deduct that it must be a lawnmower ignition. Can anyone shed some light on it for me please.
