Adjusting the idle on a Predator?

Hello all.

I picked up a new 212cc Predator engine recently to run in an old mini-bike of mine.

I loosened the throttle arm nut, and hooked up a throttle, but I can't seem to get the dumb thing to idle.

The engine engages the clutch even when idling, and it idles quite high. I can't seem to find an adjustment screw anywhere.

Am I missing something? Is there an idle stop / adjustment on these engines?

looking from the back side of the engine, find the carb. now looking on the top of the carb find the throttle valve. there will be a screw that when turned in, highers the idle, and turned out lowers the idle. you need to pop the cover off the screw (weird) and use a phillips head screwdriver to loosen it. hopefully that solves the problem.

if you cant figure it out, ill go snap a pic for you

I've been trying to figure this out glad you had the pictures. So I've turned the screw and the idle does not change it still idles at 5mph.

I think I did. The governor arm needs a spring to close the throttle butterfly. I just bought a predator and I noticed it wasn't opening and closing the carb butterfly all the way so I messed with the governor set up and now it closes and opens all the way

I was wondering and extra spring would help. I noticed my butterfly wasn't closing too. What happened to the spring that surrounded the governor linkage and attached to the butterfly? Thanks for the pic.
