os .21 rg
 

My os .21 rg has issues. when you hit the throttle it goes fine, but when you let off the throttle it takes like 15 seconds for it to drop to an idle. Please help

Your idle mixture is on the rich side. If it's too rich, the engine takes a long time to slow down. Lean the idle mixture a very small bit at a time and see how it goes.
