86 YZ250, will it start and run with a carb!

I picked up this 86 Yamaha YZ250, I was told all it needed is a carb and it hasn't run since 2015. The gas tank had the complete top missing and only holds water, leaves and there was a big Bluebelly lizard that had made it a home. I did pull the reeds out and cleaned them up and snagged the carb and throttle of a 75 250B Mx I have that needs to be restored. Will it start and run? Stick around and see.
