Not trying to hijack this post,bit my dist is not locked out.It is mechanical only and all comes in by 2500.I leave at 3000+.Should I lock it?Just figured it would start easier with less timing????BTW.36 degree timing sounds like a good place to start.If you're mph is falling off as well as et,that is indication of hp loss moreso than just et.What size jets were/are you running?Powervalves?Good luck
