I asked, because 100LL [low lead] is the most common aviation fuel found at airports in the USA. Aviation fuels all have different colors. The dye added is to prevent misfueling of aircraft. There is no such thing as 110LL in aviation. That's why I thought it was a typo. You mentioned that it's a racer's fuel. That explains the odd octane rating.
Ouch! Try using the site linked below to save a LOT of money on fuel.
Now here we have an interesting point, though not specifically about advance curves....throttle control....here I think we are all different....some have an auto sympathy and apply throttle very progressively to match the response they are getting, continually changing the setting, some prefer to think of it as a switch, on or off regardless of what the engine is actually doing in response.
Comes in small cans with pointy ears!
Obviously developed for the Gnome rotary engine....
Elf is simply a French fuel brand!

When I race my Norton, I use the throttle as you would with a two-stroke - feed it on in a controlled fashion. The bike is faster that way. If I whack the throttle open, I am more likely to get a gasp in response.. Best power is achieved by keeping the mixture right, right down the needles. It is as lean as possible, but not too lean. The shape of the needle compensates for loss of vacuun. A quicker taper copes better with bigger ports. I run the leanest Mikuni needles available, in my 34mm Mk2 Amals. My main jets are slightly too rich, so when I am on full throttle, my motor gets a reprieve. Getting the bit between 1/4 and 3/4 throttle right, is critical.
