44 john Deere model B carb trouble

Well been through just about everything on this darn tractor....... And everything ran great up to the other day when I left my chair in building with my son while I ran out in drive way to get book came back to find him playing with the carb jet screws😖
I was like "O my " anyways ,I have done just about everything I've set it to 3/4 on the load jet then 1 and the same with the idle to but seems like I just can't get the old thing back like she was ? It fires up great and runs ...... But a lot of pop crack and pow ! #%^# there is no smoke..... So intake it that had to do with load side huh?

Gently close the load screw while it is running. Keep your hand on the choke if it starts to die. Slow it down with the throttle & adjust the idle to where it idles good without the choke. Then leave it & open the load a couple turns. Open the throttle wide open and open the load to where you see a little black smoke. then close it until the smoke is gone. Fine tune it when it is good & warm after you see what it does under load. Try to keep them as lean as possible without stumbling.

Usual settings are:
1 and a half turns out on the idle mix needle
1 turn out on the load mix needle
Don't move the needles more than a click or two either way until engine stabilizes.

Well I've worked on it for few and think I have narrowed it down to the cond or coil In mag ?? Cause the tractor runs but a lot of backfire and rough idel I have checked spark in both plugs from mag and it is pour pour and try to look at mag in which I think it is shot to ?
