10201 , #39089612 cycle, hard to start hot, then runs rough

Hi all,



My problem, 10201 , #3908961 2 cycle, It is hard to start hot if it has been sitting more than 5 minutes. If I can get it going it runs rough from 1 to 3 minutes before it settles down. Been thru the carb numerous times, carb if tight and gaskets good. Just pulled off fly wheel to check seal. Sprayed top of it full of wd 40 two hours ago, and its still all there. I haven't checked the bottom seal. Where should I be looking, if not at seals?



I don't have to shut it down while mowing the yard, but it's just bothering the heck out of me, cause it isn't right.



Thanks,



Jim
