I've had ignition problems on a DLE 55 when using a supposedly "optic" cut-off switch. Problem cleared when I went to a Smart-Fly optical cut-off. Ken
If you were using the "42% Optical Kill Switch", that is the exact problem I had as well and I've heard this from quite a few others on this switch too. At first it was so subtle I coudln't tell if was a fuel or ignition issue. As soon as I removed the switch, problem solved. The Smart-Fly kill switches have worked great for me as well and are all I use now.
