X30 carburetor tryton to tillotson upgrade

I have an iame x30 with the old tryton carburetor and want to upgrade to the tillotson carburetor.

Does anyone know if buying the complete tillotson carburetor, it will come ready to just put on and race (hold pressure and pop off around 10 psi). Or will I have to open it up and adjust it to the correct spring pressure? The reason for asking this is to know wether I need to order additional service kit.

Next to the carburetor, I also need the reed cage to carburetor intake manifold and gaskets.

I did the upgrade. Mine was working “out of box”

Out of the box ready to go

Yup, it’s a drop in replacement.
