So awhile ago my 1989 cr was actin like it had no power band so I had a spare carb laying around so I threw it one there. It ran like a dream. Perfect jetting and everything. Then after not riding it for a few days I started it an it had no power. So I cleaned car Then I tried to start it and it went wot by itself and shut off. So I checked reeds and they where fine. So my question is what could the power issue be. I know that I had an air leak somewhere for the wot problem so I just need to know whats up with the carb

First off check for an air leak in the motor. If that checks out give your carb a good look over.
Its possible the carb is leaking from the cap allowing more air in.

Is there ANYTHING else that would cause this? Any weird stuff
You have heard of? Because with my luck something that never happens will prob happen on my bike...

Well I've heard of air leaks causing the out of control wot. I would check the carb since it happened after you cleaned it.
I had my last motor seize because of it running lean. The motor itself was airtight when I checked it before tearing it apart. The issue was the little rubber boot, to block off the oil injection nipple on the stock carb, had come off and allowed un-metered air into the motor. No different than an intake gasket leak.
