Only the DX12 team engines come with the new carburetor w/venturi. The D3R engines still come with the old carburetor (w/o venturi).
The part number of the new carburetor for .12 with 5.5mm Venturi is #120500-2, if you want to buy it as an optional for the D3R engine.
Performance is about the same, with a little better low end power with the regular carb.
As I told you, unfortunately I'm out of stock on them, but your old carb can be revised and it will work flawlessly again. You can dissasemble it completely, clean it up looking for debris or an obstructed passage, and change all o-rings. If it still gives you trouble we need to change main jet and main needle for upgraded one.
Since you are in Puerto Rico, did you try with the STS distributor over there?? I think it is ET Hobby Distributors.
