You can break-bend internals on the pump if you take the top off to change the gov spring, and reinstall without removing the fuel screw. One could possibly do damage with a lengthened screw if you're not careful. Now turning the idle way down, and bringing back to normal idle with the fuel screw is an easy way to get the pump close to its max settings, but always have the turbo intake hose off and a nice flat board ready if you are gonna max out the pump. Always rev the engine a couple times after turning up the fuel screw to make sure it won't run away. Sometimes a pump on the verge will idle ok after you turn it up, but when you blip the throttle it'll just keep revving. If this happens I'd first try to kill it with the fuel kill lever on the side of the pump, then kill it with a board if you have to. Easy peazy, just gotta take precautions.
