Hi Sam,all I said is that because gas is not the same today so it is not good to set it up the old way. Got it Sam.

I like to mix some 112 Sunoco in with my 93 octane Pauly. Actually even starts a little easier.

I run a 25% mix of VP 110 leaded with 87 no ethanol to bump me up in the 92-93 range-starts better, runs better...

FWIW the BTU's in a gallon of gasoline has gone down significantly in the last 30 years... it was 126,000 BTU prior to 1993 -- when they began mixing ethanol into the supply... the current BTU's for gasoline is listed ~114,000 BTU -as an aside... 100% Ethanol is ~ 57,000 BTU/gal

THIS MEANS that in order to get the same power you need more fuel... bigger jets... IF you are running any ethanol laced fuel you may have to increase jet size by 5-10% in order to get the same power out of the engine.

Lead is not relevant its octane. Lead was an octane booster but no longer.

In the older gas [leaded gas as one thing]. Today gas has more stuff in it and that changes stuff.

At the end of the season, I have race gas left over. I mix a couple of gallons in a tank of Premium and my engine will actually rev above 3500 without detonation.

If you like it that way. I found that intake manifold vacuum on the can at idle is 10 deg max,adj can that way with a tool,runs good and cylinder temp stays down too. I hope that helps.
