If you're driving a Huey sim you can't be the world's unluckiest man... you can crash and start all over... and a Huey sim at that... in your sleep!
Follow the fuel line from the petcock until it taps into a crossfeed (like a flow divider). There is a small fuel inlet strainer that could easily be clogged, if you can find it, toss it. Check the vent line (I know, it's OK), but follow it down to where it runs between the carbs. Somewhere along the line you'll find a rollover vent valve. Looks like a black fuel filter, but it's a 1-way vent valve... toss it, but replace it with something straight to connect the 2 pieces of vent line... anything tube-like will do, you just want the entire length of line so that it continues to vent under the bike. Check all the rubber around the carbs for cracks and tears, and make sure all the holes are capped (guess this shoulda been done first). The next will be to pull the carb bowls and check the jets for clogging. This would be a good time to replace the 8 bowl screws with something a little more torque friendly (hex-head screws). If all else fails and it's under warranty, get it to the shop... if it's not, call Beasly's Kawasaki in Ozark and see if they'll work on it. Most shops will work on anything, especially if it's not warranty.
Or hey, get it to the autocraft shop this weekend (long weekend). They have all the tools you need to take the whole thing down to the frame (not that you would), and should be able to check the coils at that point.
Anyway, good luck
