The only time changing fuel has ever required a jet change for me was with oxygenated fuel, c12, 110, and kemco with 91 pump mixe to 105 are the only fuels I have ever tested on the dyno (and U4 the oxy fuel) my AF readings were all almost identical as were hp readings.

I have found a oring at autozone before, it's not in their normal o ring box but one for fuel/carbs, but make sure you have the washer too and it wasn't lost when the RnD screw was installed.

The best temp gauge I have seen is the ESR

Didn't mean to answer for anyone else just trying to save you some time
