LX277 with Kaw F500V surging problem

My LX 277 with 17hp Kaw runs very rough for the 1st 1 to 2 minutes after starting. It then smooths out and runs runs fine until I engage the blades and it does the same thing almost to the point of stalling. After initially running very rough for 1 to 2 minutes with the blades engaged it runs good. I removed the carb, disassembled and cleaned it but still have the problem.
Thanks

Try momentarily pushing the choke on and see if it smoothes out.

Are you sure both cylinders are firing?

I didn't try the choke because it only lasts about 1to 2 minutes. I will try that next. Also it runs strong once it gets going but I will check the spark.
Thanks
