It is definitely a tight fit! The intake boot must be removed, and it is easiest to do by loosening all clamps, front and rear, then moving carb to the rear into the air cleaner boot, then move the front boot downward and out of the way. With the front boot out of there, the carb can be removed. I like to remove the two throttle cables . Also, check the front boot closely for rips, there have been several failures where the manufacturer cut too deeply making the ribbed design inside the boot.
