Here is a link to a reedy carb. click on the it to get the zoomed in pic. Now in the pic u will see the Idle screw to the side of the carb at a angel, make sure u are turning a screw that is in a similar place. HSN is at the fuel inlet, the Mid range needle is just below it,( If it is equipped with one) at the opposite end of the slide and the LSN is at the end of the slide( throttle linkage).

Just make sure u are adjusting the right needles first.

I'll agree with some of the posts that referred to throttle linkage issues....
Now i'm not saying you did anything wrong but some times if the trim isn't set right the servo could in fact close the carb...granted or i assume you probably have at least a paper clip width opening you should be all hunky-dory.
So you should be all good there....and peeps who are saying its the clutch are wrong....if the springs were broken it would affect anything but forward movement.

Sigh....carbs are like women...high maintenance but once you find the sweet spot....she purrrsss.

If it is more than likely its the collar on the outside controlling the throttle. Lossen the collar to relive the pressure tighten the collar when the throttle is closed. Kind of hard to explain with just words

Tony is spot on! This is your solution. I had the same problem when I first started. Trick is to set up all your linkages right and make sure when you hit brake from the idle/neutral position on your radio the carb slide doesn't move back. Also your LSN would be off, so that will need adjusting too once you've done the above.
