you could try turning top end screw in a 1/4 turn after engines started see if that helps
if its worse turn it back then restart it and turn top end screw out a 1/4 turn
if either of these improve it then carry on turning top end screw by 1/8 turns in required direction but dont overlean it
there are some engine tuning guides on the forum you could look at to get idea of what your aiming for 🍻
