You may want to revisit set the float valve height ( the height is the distance between the upper body and the lowest part of the float ,and yes it 's adjusted by bending the small tang on the float .BUT the measurement given does not include the thickness of bowl gasket ,if it stays in place in the carb body you'll need to slightly decrease the measurement.
It would seem that the slide is still hanging up . when you reassemble ,you need to be sure ,that the side diaphragm tongue (lip) is in the recess,( the diaphragm only goes in one position) that you push the outer built up edge into the groove all the way around the outside edge, and that the spring is centered in the top cap.
when you have the carb reassembled ,but before mounting to the bike,you should be able to put your finger in the throat of the carb and push up slowly on the slide,feel if it hangs up and release it and it should drop smoothly. If it doesn't , you could remove the needle and repeat, this would at least tell you if the problem is the slide or a bent needle jet.
It for sure moves freely up & down on the bench. I did it a dozen times or so while watching to see if it got hung out, or stuck or acted weird.....pushed slide up, let it fall down by itself no problems....have the carb off now & just did the same thing, no hang ups on the slide :/
Float measures, without the gasket, about 1.30", so it's bit high I think???? Paranoid I'll break that brass tab but trying to move it but I guess that's what's gotta happen!
