Easy enough to bypass, but I would certainly would not recommend it for the same safety reasons it exists.
Take it off and try spraying contact cleaner or WD40 into the area by the plunger, I have done this and it has brought a few back to life after operating it numerous times by hand. Many give trouble because the corrode from lack of use
Same as the Carburettor model R6
Later 04/05 ones were upgraded
