There are five stable isotopes of nickel: Ni-58, Ni-60, Ni-61, Ni-62, and Ni-64. Properties: The melting point of nickel is 1453Â°C, boiling point is 2732Â°C, specific gravity is 8.902 (25Â°C), with a valence of 0, 1, 2, or 3. Nickel is a silvery white metal that takes a high polish. Nickel is hard, ductile, malleable, and ferromagnetic. It is a fair conductor of heat and electricity. Nickel is a member of the iron-cobalt group of metals (transition elements). Exposure to nickel metal and soluble compounds should not exceed 1 mg/M 3 (8 hour time weighted average for a 40 hour week).
Quick Answer. Symptoms of a bad ignition module are sudden engine stalling or power loss while the car is in motion, engine stuttering accompanied by a smell of gasoline and an inability to restart the engine following a stall. Decreased gas mileage is also a sign of a compromised ignition module.
If the small engine is hard to start the spark plug might be defective. All small engines have an ignition coil. The coil is the device that provides spark for the spark plug(s).If the coil is bad power won't get to the spark plug(s).H690/0016.
