first thing is you need to remove the flux capacitor to get to the kunoyter valve. Once you see the kunoyter valve your gonna have to turn the rock welder around five times in a bottle of water to make a good flight path about 3 times. If all goes correctly you should see where the blinker fluid reservoir hides the access panel to the muffler bearings. Remove both of these and there you'll find the spark plugs. A good 16/32 mm deep standard SAE metric 3/8 drive 1/2" impact socket should be the correct tool to undo the plugs. Oh, and remember, turn em clockwise to get them out. Good luck!
