What carb. should I buy?

I follow Dominic on Facebook and his stuff is awesome! Looks like jewelry.
Yeah, like jewelry and performs right out of the box. Only screw i turned was the throttle screw about a 1/4 turn to idle faster. Later i had a lean transition that i cleaned up with different T slot jet. No big deal. Everyone has a different combo and will require a turn of the throttle screw or mixture screws or perhaps jets. Dom gets them right on or atleast very close.
