Hey techinspector1
Thanks for that info and link. I really don't want to retard my cam timing althogh I have considered retarding the ignition timing. We have 94 octane readily available at the pumps here, so I am wondering if 94 and maybe 33 degrees total would be user friendly for my motor. I am currently running 35 degrees total with 100 octane. When I have tried 94, I get engine run on.
