I have the exact same setup.

The ID on the carb is 19mm. Although you need to TAKE OUT that plastic piece to make it 19mm. It is much smaller diameter if you leave it in there.

The OD of the Intake on mine was like 22mm. The ID on the intake is ACTUALLY like 18mm despite the advertised 20mm.

Since the OD of the intake is 22, you'll need to shave off like 3mm on the rim of the intake so it will fit. You do not shave the plastic piece.
