Jetting, and a Question about new cylinder

I sprayed carb cleaner on exhaust manifold and intake manifold but didn't change the high idle. It's like I can rev it up and it revs back down slowly. Maybe the 2 seals? I ordered 2 viton seals from hybrid.. didn't check the head gasket though...

Is your throttle cable hanging up or a weak return spring?

No it has a good snap back when let go, it's definitely a air leak I think, when I rev it or am going fast then pull in clutch it idles high but slowly goes back down. It was doing that with the stock carb on too before I changed to the pwk21. I don't know how many times your supposed to use the copper head gasket but I've had mine off and on several times, checking squish and stuff. Maybe could be that? I order some more.

And it was doing that with the other cylinder before putting the ported one one so that's why I think it's possible the crank seals. Gonna take off both covers and spray water mist when it's idling to see if that's it.

I just hope it's not deeper than that cause that's where my mechanical brain stops and don't know any further lol

I really appreciate all the help. If it wasn't for this forum I couldn't have made it this far. I apologize if I ask too many questions and off the wall stuff that doesn't pertain to subject. I'm a little ADHD 😆
