If your sure it's a carb problem; it's ignition,

Getting the carbs back on. This is my method.
Put a tiny bit of Vasoline speared on the mating parts.
Get on the right side of the bike and tie the carbs up with zip tie to take the weight off.
Then push the #4 carb into position all the way and tighten the clamp.
Then go to the left side of the bike and push the #1 carb into position all the way.
Tighten the clamp.
The two middle carbs should take care of themselves.

Thanks, Lucky!  This method worked nicely...
