No. I've tried changing the ignition timing numerous times. Change a couple degrees. Test Repeat. I will change when the atmospheric valve opens. Don't know if that has anything to do with it or not but I will try anything at this point. I will experiment making it close sooner by bending the tab. My bog goes away when I close the manual choke about halfway. I keep changing the idle mixture screws. Seems to me I should set them richer since the choke is essentially making it run richer. Does that seem logical?
