CNS Carb suddenly started idling very high

I've been riding off and on most of the day. Put about 60 break-in miles on the new engine (it's got about 170 miles on it now) and it was running like a champ. Then, as the sun was beginning to set and I was on my way home (about 5 miles out) the carb just started racing like crazy. I pulled over, checked to make sure it was tight. It was. Took out my tools and fired it back up. It seemed fine... idle was normal and gave her a little gas and it was like the throttle was stuck WO. Hummm....

Had to adjust the idle screw way down to get her home... hobbling and bogging.
What a bummer way to end the day.
So got her home and I'm gonna let her cool down tonight. But first thing in the AM I'm going to be trouble shooting.

Anybody with a similar scenario?

That has happened to me, once or twice, today..
It was because the low gas flow to the carb.

Hmmm... Guess I'll look into that after I test for an air leak.
Thanks

Yep. I'm pretty sure I'll be ring gasket hunting tomorrow. Ace HW better be at the top of their game when they see me I tell ya!

After carefully selecting my sealant of choice and thoroughly cleaning all surfaces, I finally began the task of CAREFULLY and NEATLY applying the wonder jelly. I must say, you can hardly tell there's any gasket goop on the carb. I did a really fantastic job.

And then I noticed my bolt was stripped. Probably the cause all along. ...gdath
