Just realize what the slide position sensors do before disabling. If there's a mis-match between slide position in the carb and throttle position, (like when the slide ices up and sticks in the wide open position and you let your hand off the throttle expecting to slow down) the safety switches in the throttle block and the slide position sensor switches will kill the engine, preventing a run-away sled.
Hooking the wires together still attached to the wiring harness defeats the safety switches. Be quick on the kill switch
Lots of guys disable the carb switches, they can be a pain in the rear.
