I have a question about a stator on a rotax 500. My problem is a very weak spark, which leads to hard starting. Everything has been gone over. I noticed the 3 small coils on the stator that control ignition spark look slightly overheated. The biege insulation looks like it might have been really hot at some time as its seems burned from the inside. Would this be a bad stator, even though it is still producing a spark. Thanks for the help.
