interesting carb on the bay

You won't get many hits on that carb in particular. You'll find plenty if you look for Webra Dynamix which it's a copy of. Your carb has a "remote adjustable" needle. The lever on the main needle adjusts the mixture with a servo.

Echo what dieselpilot says. I ran them on 0.60 size 2-stroke RC pattern models for a few Webra seasons back in the day. They worked but did require some adjustment learning, not quite as plug-n-play as the typical Japanese carbs. I do remember them being fussier about fuel pressure boost (typically pressure nipple off the tuned pipe or crankcase, sometimes with/without restriction or check valve). But typical aerobatic flying conditions make more demands on carbs vs stationary engines - range of high speed, low speed, transition, varying attitudes & G's resulting in wider fuel pressure swings. Once I went to YS timed diaphragm regulator, I never looked back.
