For these reasons, healthy levels of magnesium have been linked to deep, undisturbed sleep. Consequently, low levels of magnesium can contribute to frequent nighttime wakings. Magnesium deficiency has been linked to several insomnia-inducing conditions, including restless leg syndrome (RLS) and night terrors.
Scuffing is another condition that can damage pistons. Scuffing is often the result of overheating, but loss of lubrication, detonation and preignition can also be contributing factors. When an engine runs hot, the pistons swell. This reduces the clearance between the piston and cylinder walls. The cylinder bore can also distort adding to the problem.
The carburetor itself can cause flooding problems, too--particularly the float valve (needle) and seat. As you operate a piece of equipment, it transmits a lot of vibration to these parts. The vibration causes small ridges to form on the float valve.y adjusting the tang, you can prevent carburetor flooding, hard starting and poor fuel economy. To make this adjustment, drain the fuel from the carburetor and remove it from the engine. Turn the carburetor over so that the weight of the float rests on the float valve and seat (see Figure 3, page C 46).
