Default Power valve

Hi all, in my quest to get the ec250 running right. a mate said is the power valve sticking. Can I ask what this feels like and have any of you guys had this happen.

So far I have tried. 38 pilot,170 main, n1ed needle #3
42 pilot, 178 main and N1ED needle #3, #2 and #1
38 pilot, 175 main and N1ED needle #2.

It tops out at 50mph and seems to cough and spluter. It idle but only just with the adjustment screw nearly spring bound in.

It is running std sprockets 14, 48.
The starts first kick and reeds are new.
