Hi john,
I believe it is your starter ad= aptor that is slipping. Mine produced the same symptoms when it failed. = ;

I think the Iskra starter damaged your starter ad= aptor and then the extra torque provided by the Skytec starter finished the = job. This has happened to enough Cirrus owners that many shops now recommend= a preemptive IRAN on the starter adaptor when changing from an Iskra to one= of the newer starters.
