Unhappy One carb floods the other one is dry

Ok guy n girls... finally had 5 minutes to drain out the old gas {stinky but not super bad}. I drained it all thru the carbs {used my hand vac checker to make sure gas valve is working right, it does} pulled the plugs and sanded em down for a good spark and tried it.
It would kinda hit a pop or 2 with no throttle but wouldn't actually run.
I'm gonna get some new plugs but I expected it to actually run.
I pulled the filter/carb boot off on the "left" carb and it was soaked. {of course I was playing with starting it on choke and wide open and no throttle on choke, wide open with choke whatever combinations you can think of}
So I pulled the front plug out and cranked the engine and gas was spraying out of the hole. I got it all dried out on both jugs and it still wouldn't start.

So I guess I'm asking if there's some special tips/issues on the carbs that are unique to this bike that make it flood and/or hard to start.
Thanks

The usual first question with hard starting is what kind of battery do ya have?
An old, wet cell battery could be low on acid, causing difficulty in starting.
New plugs would be better than sanded old plugs. Ya may have opened the gap a little too much.
Have the airfilters been cleaned?

Well, got new plugs but no time to put em in yet, probably over the weekend. The battery holds a charge well and cranks well so unless I need ALOT more than that to get it going, the battery should be good.
What is the gap supposed to be and I never even looked at the filters. Are they behind the covers on the sides?

It's possibe that the float in the left carb is stuck in the open position allowing gas to overflow the front carb. You could try draining the carb then spraying carb cleaner down the fuel line to see if it clears any thing up.
