I hate to tell you this, but your engine, although supercharged and unmuffled, just won't do.


Someone once mentioned the need for an emergency cutoff switch. As mine had been 100% reliable, I first thought that to be ridiculous. On second thought, though, the remote possibility of 200kg metal tank out of control in a public crowd with the kids closest (tends to be that way...) made me realize that it really is a good idea. I made mine by resting the rear louver on the switch, so that simply pressing it down a millimeter or two cuts (or engages) power. Very practical and convenient, it has turned out. You can do that with your mechanical variant if you position it right.
