setting up the scootopia sh2/22
my s-2 w/gp engine has always had the o.g. sh2/22 delly on it and runs pretty good. decided "up grade" to the scotopia carb since mine were so old. pretty much the same carb but i wonder if the idle mix screw is to be set the same as my current carbs (1& 1/2 turns). i know that the jet-x carbs (the ones that work) is only a half turn to dial in. has anybody gone scootopia and dialed theirs in? is 1&1/2 good do ya think? i have twiddled around w/the mix and think i have it fairly smooth but someone that has one of these would know better so if anyone knows please do tell. thanks in adance for the help!

I have a similar set up
PHBL 24
BGM 195
BGM Sport, but was a clubman until the bracket broke
I am also at sea level but in California
I messed with it quite a bit, but this is where I ended up:
Dellorto PHBL 24
Main 102
Atomiser Aq266
Pilot 50 *Changed from 51 after sport exhaust 03/16/24
Needle D26 3rd Clip Down
Float 300
Slide 40
Plug BR9ES
For the most part I got it close myself but wanted a professional opinion and the guys a scooter speed dropped the main from a 108 to the current 102.
Another thing to note is the 300 float, my carburetor came with a 200 and I was told this could have the potential for fuel starvation, which is obviously a lean condition.
Good luck!
