Welcome to TMBF mate. . . . . pop over to the Newbies section and introduce yourself to the guys when you can. .....

So, when you rebuilt the carb did you set the needle height correctly.....and is the float set correctly too.......sounds like fuel starvation ......maybe blocked main jet too.....

I put the needle in the slot on the float not sure if that's right though but when I move the float the needle does rise and lower accordingly

Make sure that all tubes and pipes are air tight, as there is a chance you are pulling too much air from somewhere, giving you a weak mixture.
