First off Welcome.
The reason we don't the choke/enricher is cause it does just that, fouls plugs. If you have to use it cause its really cold, then ok, but get it off ASAP.
First off I would ensure your plugs aren't fouled again. Then get it fired up. Get the bike and carb warm. Then time to adjust it.
You can use the below links and my little typed out version

S&S Carb Manual

To adjust the carb... with the bike warm...
(in=clockwise/out=counter)
if your idle is low... turn it up a bit...
now spin in the accel pump screw till it seats. Now spin it out 1.5 turns
now spin in your fuel/air mix screw till the motor sounds like it wants to die
now spin it back out counting 1/4 turns. Do it slowly to give the motor/carb time to adjust. Do this till the motor sound like it wants to die on this end. Now you have counted those turns and you have say 2.5 turns. Spin it back in 1.25 turns. Or middle to almost dead on each end.
Now adjust your idle to 1,000 rpms on the tach.
Now with a few quick stabs at the throttle see if the rpms come up fast like you would think or if it kinda hesitates then takes off. If it does hesitate then spin the accel pump out another 1/4 turn and repeat till you get what sounds good.
If that don't fix the sneeze... you can spin out the accel pump a bit more... but anything over 2.5 turns means you need a larger intermiediate jet.
