carter bbs float adjustment

Was wondering what your guys float levels are on your carter bbs i currently have mine to 7/32 i was messing with it the other day and set it lower due to my car running at 180 degrees instead of the 195 degree that's installed in my thermostat finally my car would reach 195 degrees and run a lot smoother has anyone ever had this problem or any ideas? would running the float level a little leaner be bad in the long run? Could this because of too much advance on my distributor that i have to mess with the float?
