Think of voltage as electrical pressure; amperage as the volume of electricity flowing; and resistance as electrical friction that resists current. Direct Current or DC is electricity flowing from a battery. Alternating Current is electricity flowing from an alternating power source such as a stator.
The starter solenoid is a relay switch that contains 2 circuits and has 3 or 4 wires connecting to and from it. Two of these wires are heavy gauge, and the remaining are smaller gauge. The two heavy gauge wires are connected to your starter and to your battery. The remaining small gauge wires are connected to the small terminals on the starter solenoid and lead to the ignition switch and to the common ground. If your starter solenoid only has one small wire or terminal, the ground is through the solenoid’s mounting bracket.
You may have heard of the term “grenade gears” when researching the Kohler K series engines. Even I have heard many people proclaim they throw the balance gears out when rebuilding their engine, and that they don’t do anything anyways. When asked why, people often site some anecdotal evidence of gear failure they heard through an internet forum. It seems to me that few small engine enthusiasts understand why balance gears exist, why they are important, and what causes premature failure. I hope this article can help you make an informed choice when rebuilding your engine.
This can be illustrated with this math formula: Force = Pressure x Area.So if we were to push liquid at 1,000 psi into a cylinder with an end area of 2 square inches we would produce 2,000 pounds of force. If we were to enlarge the end area by using a larger diameter hydraulic cylinder with a 4 square inch end area, we would produce 4,000 pounds of force. Since the displacement of the larger cylinder will be greater, our cylinder will move slower but with greater force. Like all other forms of mechanical advantage, we trade speed for power.
