DaveI've had good success with the ignition system from the Jerry Howell site. I've used the 6V coilhttp://www.model-engine-plans.com/partskits/ignitionsystems/coil.htmand the electronic ignitionhttp://www.model-engine-plans.com/partskits/ignitionsystems/transistors.htmSoldering it together is a piece of cake and you can buy an extra magnet for your two cylinder set up.http://www.model-engine-plans.com/partskits/ignitionsystems/sensorsmagnets.htmI don't know how well it compares to other stuff out there as it's the only one I've used. Maybe what Steve Hucks recommended would suit you better. Just another option.Steve
