When I was playing with the jetting on the 50 I put the needle 1 click under the stock setting. It ran great in the mid but suffered in the top end.

Is there a way to combat this with changing the main jet? It would scream from 1/4 throttle thru 3/4 throttle. But would kinda bog down with full throttle. I let off the throttle a little and it started screaming again.

Sounds like you are too rich on the main jet...Needle is for mid range....

try dopping it down to like a 95 MJ.....Stock in the PE20 is a 100 I believe
