Bought a new carb for mercruiser 305. Fuel was burning rich. I went to adjust and had to turn screw at least 4 times to seat it them backed it out 1.25 turns as per manual. Was running great. Then it start to burn too rich again. Checked adjustment screw and had to turn 4 times again to seat it. Its apparently coming loose and maybe the vibration of the engine. Any suggestions on how keep it at 1.25 turns
