best case hope for saturated plugs or cylinders. you may let the cylinders air out a bit before using the new plugs. if your in a hurry, torch the fuel out.
although rare, its not uncommon for some cranks to go out of phase. not brand specific at all but more the nature of the 2 stroke design.
quick way you can check yours to rule out a timing or crank phasing issue is to simply use a wooden dowel, welding rod, or anything thats straight and rigid.
using the clutch side cylinder as a guide line, roll the engine over slowly until this piston comes to tdc. with this piston at the top, the center and mag pistons should be equal in depth from the top of the spark plug hole within .5mm of each other, +or - either direction.
anything beyond that may require some more accurate measuring or it could indicate a problem. dont sweat yet, other underlying problems can create the issue your describing. before chasing your tail, measure the crank.
