Spark plug diagnosis

While adjusting my mixture I did accidentally turn the driver side mixture screw all the way shut and it didn’t stall out. I wonder if it is still running off on the power circuit. I to can still lower the idle using the idle screw if I increase the timing.

I feel like a blind squirrel working on this. I was able to loosen my idle screw more and advance my timing more to keep my idol at the same rpm. But it still seems like my mixture is not as adjustable as it should be. When I have my idle set to 700 it will turn off if I tighten the mixture screw down all the way but other than that it doesn’t seem like there is much adjustment. At 700 rpm it seems like I can adjust my timing and it doesn’t do anything to the idle speed. When I raise it to 1100 rpm adjusting the timing seems to change the idle speed.

Thank you guys for your help. I got it turned better than it has been sense the carb was installed.
