98 sxr engine rebuild problem

[yammies]

hi i have a 98 sxr 600. the center cylinder blew on it. i put new jug and that cylinder then installed new piston and rings on the top end. went to start it and the sled is only running on the two outside cylinders. so i cleaned carbs (which weren't dirty at all). stared it again and the same thing. compression is 120psi. so i changed the coils and put new plugs. the cylinder is getting gas you can see it start to drip out of the header. This has me baffled it shouls run i have spark,fuel,and copression. Is it possible the base is flooded???any help would be greatly appreciated.
