Cat 10 carb

Where are the leaks?, Need more information to make any recommendations

you must file all flat surfaces to get the gaskets to seal properly.

Your gaskets are mabe too thin.
Use 2mm corc-neoprene for big lid gasket and for on top of pedestal inside.and find out how thick the lowest gasket ( just a o ring will do) should be, mount pedestal without any gaskets and measure how many free play pedastal has with with checking free play with screw G. That must be thickness of lowest gasket, then put the 2mm gaskets on top of pedestal and for the big lid.
Ones you know the trick its not soo difficult...
If by any reasons you want to sell your carb let me know.
A new mavel slebner carb with 90 degree elbow will do aswel.

Do I understand correctly a marvel slebner carb with a 90 elbow will fit?

Yea. To replace the broken carb of my ten I bought a brand new carb on ebay and made an elbow and fitting oval to mount on the engine.
