We do not know. Look carefully at the breakdown diagram that comes with the carburetor kit.

Another cause could be the wrong jets. Ensure that the new jets are the same size as the old jets.

Metal seems to be missing at the edge of the screwdriver slots on the jets. This damage results if the screwdriver is:
1. held at an angle to the jet.
2. not fitting the jet snugly.
3. overtightening the jet.

If you want to remove those jets later, they may break instead of unscrewing. The purchase of a new carburetor would then be required.
