1978 Yamaha EX340B

Hi i'm kind of stumped, my sled idles but as soon as i try opening the throttle, it bogs down and will die after a few seconds, i've cleaned the carb good, put in a new float valve, checked the float height, it was good, put new engine gaskets on, tried new spark plugs, i can't figure it out. I've played with the idle mixture screw.

I forgot to reply to this, anyway turns out a little mouse was helping me out by living in my exhaust pipe, soon as I cut the pipe apart and removed the nest, it worked good.
