Be careful with the screws from electrical fittings.

They will work but there is two different threads around, so make sure they fit nicely.

Use two screws and tap alternately and only enough to move slowly. Better still find something you can use as a drift to strike both screws at once.

As said before, remove all the jets and the main jet stack and the throttle slide screw.

Hopefully the plastic liner has already detached from its glue and will come out.

When you re assemble, be careful not to overtighten the main jet one that only has a few threads on it.

There is a gasket under the venturi so be prepared to replace it.

You can use the screws to help align the venturi once you get it so far down.

Get it as even as you can, it does affect the carb performance.
