So maybe another tuning lesson learned? I'll ask you guys opinion first. So I've fought and I've fought, and I've fought with the carb/timing issue for far too long and I figure I'm fixated on one thing while the issue is quite something else so I decide to wave the white flag and get a fresh set of eyes on this tuning issue and I take the GTO to my local speed shop to have a pro give it a once over. So he pulls out a modern fancy star trek looking timing gun with LED readouts and dials and whistles on it and proceeds to show me that what I thought was 14 degrees of timing was actually set at 21 degrees of initial timing and 41 degrees of total timing. wow so in your opinion are my eyes that bad? or could there be a 6 degree difference between 2 different timing lights? The ride on the way home says thru the butt dyno that I picked up 50 HP with zero pinging and a much less strenuous sound coming from the starter on hot restarts. I still have some idle and off idle carb issues but that might have lead to a suspect PCV valve that I plan on replacing when I get back to work on Monday. Do I reserve trust in my trusty timing light? Or is a new set of contacts in order? 14 degrees is only 2 degrees off my timing tab so I don't think I could have been that far off, whats your thoughts?
