I have an Electroair EIS ignition which uses wasted spark coils on an IO-540 and it has been great for 300hrs. When starting today I got what I think was an after fire (ignition on the exhaust stroke) just prior to a normal start. I can see this happening if conditions are just right; like the old days when we would turn the ignition off then back on and get a "backfire"
Since this is a first for me, has anyone else with wasted spark ignitions had any similar problems like this when starting. I did not have a kick back, just a loud firecracker like bang then a normal start. Thanks Barry
