This was happening to me. I was running idle at around 2400 rpms.
I'm not exactly certain what it is called, but there is a accelerator 'trigger'(sorry for my crappy lingo). You loosen the bolts to the immediate right of that and the idle will run at different RPMs.
don't do this if you have no idea what I'm talking about, no telling what a simple mistake may do when it's lost in translation.
