Default Any ideas why car may be over fuelling on one side?

Hi just after some ideas why after swapping the engine the car is over fuelling on injectors 2 and 4.

it's kicking out alot of black smoke so decided to check the plugs and replace the plugs with new. Ngk platinums. 1 and 3 where a little black but dry. 2 and 4 on the other hand were black and wet. Smelt like fuel. Just after ideas of what to check. It's a classic impreza 2000. I've got some one looking into it but feel useless so looking for ideas as to what it could be. 🤔

any help muchly appreciated thanks

Possible blocked injectors or fuel feed lines for the other bank?

I've replaced all fuel lines due to previous owner using the wrong type of braided lines. I'm thinking it could be an injector issue maybe. Will try and get them off to have a look this weekend.
