first verify that my artwork is right.
#8 is MAB......?
Help me to understand all the rest of them holes/numbers between my fuel and air red circle.
Numbers 22,23,24,25 View attachment 1715368717
THIS IS NOT MY CARB! IT'S FROM A BOOK OF THE 80'S
The main air bleed is in the main body. It's the smaller of the two. The bigger bleed is the idle bleed.
23 looks like it's pointing out the emulsion channel.
The bottom and middle 22's are the emulsion holes. The upper 22 is the kill bleed.
That is a 2 emulsion block. Those are generally .026 holes. Evidently your Demon block has three of those and all three are bigger than .026 which as PRH pointed out is a lot of emulsion.
I think 8 connects to the MAB in the main body but to be sure I'd rather look a onto my blocks in the shop to say for sure.
