I wouldn't worry about it since you answered your own question as it runs great, but you sound like me, just got to know. There should be the normal marks on the fan and if you look real hard they can be found. I painted each one a different color on our 2.0l so I would know which was which. There is a new tech article about timming with carbs in the "new" section here and 34 to 36 degrees seems good. I use 36 degrees on the race motor and use 103 octane gas too and it doesn't ping. The RPM timming is done at has to be high enough sso that full advance of the weights occurs. Good luck.
