Feroza/Sportrack Carburetor - what is this?


Hi Everybody! Could anyone tell me please what a nr 4 and 3 on carb and where to connect this?, also nr 2 on pump. Im getting crazy with this,my car with current connection don't has acceleration after I changed carb in garage. Manual dosn't says much, I coloured what Iam sure according to this but it could be also wrong.
Please share your connections on your carb so once we can do final diagram, I found people looking for this.
