You need to start by setting your af at wot. Usually you don't want more than 8 jet diff between the pri and sec. The power valve on the pri side makes up the diff. With good aluminum heads like you have you want between 12.5 to 13.2 depending on the motor combo.
Once that is set you can adjust the idle mix. The fuel that flows through your idle circuits is present at all times and has the biggest impact on your part throttle af. You want it as close to 14.7 as you can get it. That being said, now completely disregard it. Due to the performance nature of our engines that is not usually the case. Especially with a carb. In reality you will probably wind up closer to 13.5 or maybe 13.7 would be my guess.
Having done that see how the drivability is at low speeds to cruise. You may have to richen it up if it has flat spots. A tip in stumble can be cured by changing out the squirters. More on that in a min.
Next I would work on the transition from part to full throttle. Remember wot af should be good because you already set it. The transition can be smoothed out by changing when the power valve opens. To lean means you need it to open sooner. To rich means delay it a little. Ideally when you punch the gas from a stop you want it to go to 12.7 to 13.2 and stay as flat as possible through all rpms.
If you have a lean spot when you punch it now is the time to adjust the squirters to the same as the wot af. To rich and you use unneeded fuel and loose some power. To lean it stumbles and that's no good.
Once you do all of that it should run pretty good and get you the best mileage power compromise.
I have the same carb and got it to run great doing that. It took a lot of jet swaps, squirters changes, etc. If your serious buy some gaskets, a jet kit, maybe a squirter kit, and a data logger. I used the lm1 and recorded passes then read them on a pc. Takes notes and make one change at time. Don't forget to keep the jet spread equal and take your time playing with the idle adjustment. I will upload some graphs when I get back on Sunday.
Have fun! I love this demon carbs and you can get them really dialed in. My model didn't come with air bleeds but that would be even better. Good luck.
