Thanks to all of you for your suggestions, here's where I am now:
Yammer, I don't know much about carburation to know what action to take about your response "Are the pilot jets still plugged? "
Randya, I've changed the spark plugs & checked the wires, all cylinders seem to have good spark, and as I said with the air box top off it runs great
Mbrood, last night I tried running with the filter out & the lid back on, and it's awful, no decernable difference with the filter in or out with the lid on, I guess that means the filter isn't the problem.
Mrich12000, that sounds reasonable to my uneducated mind, I assume I'd need to get the "kit" from my dealer(?). My assumption is that it is getting way to much gas to run with the normal air intake.
Additional info: I noticed while messing with it last night that the outside of the #1 boot only has some gas, or something wet on it. Also, the carb drain hose on #1 is cracked & won't stay in place, I assume this isn't a performance issue tho.
Thanks to all of you!
