How does using a Non-resistor spark plug increase or decrease?

resistors in a spark plug decrease the amount of current that’s allowed to flow to the electrode. By using a non resistor plug or by removing a resistor out of a plug yourself will significantly increase the voltage and current across the ground and Electrode there for creating a much hotter more intense Spark.

What happens to the current when you add a resistor?

But notice that total current changes when you remove or add a parallel resistor. Emf source has to provide the current to all the resistors. The power delivered by the EMF source also changes when you add or remove a parallel resistor. Thanks for contributing an answer to Physics Stack Exchange!

Why do I need a resistor spark plug for my riding lawn mower?

The result may be a loss of engine performance, misfires, or a rough idle. If your mower has an electronic ignition system or computer-operated sensors, you likely need a resistor spark plug. Manufacturers suppress ignition noise by including a resistor material inside some spark plugs. Resistance is measured in units called ohms.

How is the resistance of a spark plug measured?

Resistance is measured in units called ohms. One concern about resistance is that it does affect how fast or how effectively electricity travels across a distance. Spark plug resistors operate in the range of about 5,000 ohms. This is a high enough amount of resistance to cut down on ignition noises,…

What was the use of resistor plugs before radio?

Resistance in spark path was used before radio was common, before RFI was an issue. Most motors are inherently RF noisy regardless of resistance in spark path. Its shealding and grounding that prevent electrical systems from picking up the noise. Acception to the above is old carbed diesels. They use old checkers around radio telescopes.

Is it OK to use Non resistor plugs on an OHC 230?

In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion. Still running the stock OHC 230 motor? If so get non-resistor plugs.
