Default TM45, throttle return... not coming back to idle properly

Okay...
Now that I got the DS out of storage... and she runs beautifully...

The return spring on the carb won't bring it back to idle all the way. I have to snap the throttle open for it to return, or do it by hand and it comes back. Seems the tension on the spring needs to be a tad more... and it'll be perfect.

Ideas??? How to gain a little bit more tension, or if there's a way to make the throttle come back easier, as the cable has the slack it needs when closed.

HURRY carb gurus!!! I'm on my way out Monday!!!

Thanks, and Happy Holidays!!

Heard of them getting caught-up on the seat. . . you may want to do a search or cut your seat pan a little.

Yup... new of that, and this is all with the seat off the quad... nothing binding.

It's something to do with the carb itself. Or the spring.

Do you have an accel. pump enabled? Check the linkage?

How's the slide look. Not gummed up?? I know. . . obvious stuff.

try lubricating your throttle cable, and check your thumb throttle, maybe something is binding or "hanging up" on something somewhere

Hmmm....
I'll check the slide, could be something.

Accel pump is enabled, linkage is okay.
Twist throttle with pretty much new cable. No binding.

... this quad is like brand new (check my garage) ... so it's not the common issue things to look for. Since it's been sitting, the slide is a good thought. It doesn't stick when it's ridden, it's only seat off in the garage kind of thing. You give it a slow rev and it will not return. When it's ridden, the jarring and vibration helps it return and you really don't notice it. Or, you snap the throttle open and then closed and it won't stick... it returns okay.
