Tiger, if you choose to bypass the original kill switch system and opt for a remote on/off switch make sure you plug the the hole in the carby where the wires originally go with some silicon or something but dont push too much in there otherwise it will interfere with the throttle operation.
Having said that the cutoff boot/grommet kit is only $4-$5 from your local mower shop and will alleviate the hassles of silicon, wires running up the handle bar, mounting a kill switch, etc, etc..
