There is a magnet on the side of the flywheel that passes the engine's magneto, which causes the spark plug to ignite the gas in the piston. The flywheel is held onto the crankshaft by the flywheel key.
Triphenylmethanol (also known as triphenylcarbinol, TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene.In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.Many derivatives of triphenylmethanol are important dyes.n strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.

I use butyl carbitol (Diethylene Glycol Monobutyl Ether) mixed with water as a cleaner. This is a water soluble solvent that isn't too bad to work with. You can also add sodium carbonate or sodium hydroxide for more cleaning power if needed. I use these solutions in a 30 gallon heated tank with a Branson ultrasonic driver and transducers.
