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.

Hydroxypropyl Methylcellulose is non-ionic cellulose mixed ether made from refined cotton by alkaline treatment and then by a series of reactions with propylene epoxide and methyl chloride as etherifying agents.The degree of substitution is generally 1.2-2.0.. Hydroxypropyl Methylcellulose is easily soluble in cold water but difficult to be soluble in hot water. However, its gelling temperature in hot water is significantly higher than that of Methyl Cellulose (MC). And compared with MC, the dissolution in cold water has also been greatly improved. 2.
