YFZ450 Stalls when I give it gas

hello,

I have a 2005 YFZ 450. Currently everything is stock besides a K&N air filter. The jetting is 45 pilot and a 168 main. I just replaced the entire carb with a refurbished one (one that came off a running yfz 450 and was cleaned). I installed it and it idles fine. I don't have the throttle cable connected yet, but when I move the throttle on the carb to give it gas in stalls instantly. I posted a video on Youtube for you to look at. Please let me know any input anyone might have. The like for the Youtube video is

Thanks in advance!

Please bring this thread back to life, I'm having a similar issue. My TPS is installed but I dont know how to adjust it or if it is necessary. What is the adjuster wheel on the back of the TPS housing meant for?
