The Neway Valve Seat Cutters I use are a manual cutting tool. It only requires finger pressure to make the cut. These cutters hold carbide cutters at perfect angles for cutting your valve seats. Depending on your engine you may need to cut your valve seats with a 46 degree...

Measuring resistance can indicate the health of a component. For example we can determine if an ignition coil is healthy or not by measuring the resistance of its windings. To measure resistance, set your meter to Ω ohms resistance. If you need to select a range, select the smallest range...

Workshops manufacturing parts in PVC or rubber use high-frequency welding processes to perform assembly. The propagation of strong magnetic fields and high-frequency waves is not easily controllable....

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...

Wires and cables (conductors) are insulated and protected by a variety of materials (insulators) each one having its own particular properties. The type of material used will be determined by the designer who will take into account the environment in which a control panel or installation is expected to operate...

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb....

When your engine is operating, your stator produces an alternating current by means of electromagnetic induction. This alternating current is fed to your rectifier/regulator by two wires. These two stator wires connect to the AC – and AC + terminals on the rectifier/regulator. The rectifier/regulator converts the alternating current into...

To solve the leak into the atmospheric vent make sure your float level is adjusted perfectly. The float should be perfectly parallel to the upper carburetor body or sit slightly lower than level. This keeps fuel below where the two halves of the atmospheric vent meet. Also make sure your...

Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller....

So your tractor lost spark. You purchased a new ignition coil. After you installed it you still don’t have spark. What happened? We will go into this common problem later in the article, but for now remember never make assumptions. Always look for evidence that suggests a cause. Evidence comes...
