The main issue with the PZ30B pumper carb is its width increase due to the pumper diaphragm actuator...


The other main pain with the PZ30 is the under bowl position of the A/F screw which is a PITA...
If you buy them off of Amazon, the AF screw sits outside the hole by about 1/4th to 1/8th of an inch. On my Vader 150, I can easily adjust with a small flathead screwdriver.



...

And why would you hacksaw the bowl off? Because if you have a newer bike, you won't be able to create a slot in the screws, without damaging the (OEM carb) bowl anyway, in such a way that it would leak. They are 3 to 4 mm deep in the bowl.
