Finding the model number on a Briggs & Stratton engine is essential for obtaining specific parts, service information, or instructions. Typically, the model number is located on the engine itself, stamped directly into the metal or on a sticker. For most models, you'll find this identifier near the spark plug or on the engine's housing above the muffler. In newer engines, it may also be located on the valve cover. The model number is usually part of a larger code, which includes the engine series and type, providing detailed information about the engine's specifications. It's crucial to refer to this number when seeking technical support or ordering replacement parts to ensure compatibility. For precise identification, clean the area around the presumed location to make any markings readable, as dirt or wear may obscure them.

Nitrogen tyres and air-filled tyres have several differences. These are:

1. Purity: Nitrogen-filled tyres contain about 95 to 99 percent nitrogen. On the other hand, the air we breathe (and also use to fill our tyres) is about 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases.

2. Tyre Pressure: Nitrogen molecules are larger than those of oxygen, which means they are less likely to leak through the tyre rubber, helping maintain tyre pressure for a longer period. Meanwhile, oxygen in tyres escapes more quickly, hence the need for drivers to regularly check on their air-filled tyre’s pressure.

3. Moisture: Nitrogen is usually dry, while air contains moisture. Moisture can lead to wheel corrosion and variations in tyre pressure with temperature changes.

4. Cost: Filling tyres with nitrogen can be expensive compared to using regular air.

5. Availability: Air is widely available at petrol or service stations. But special equipment is needed to fill tyres with nitrogen, and not all stations may have this.

6. Fuel Efficiency: Due to more stable tyre pressure, nitrogen provides more fuel efficiency than air.

7. Tyre Life: Nitrogen can prolong tyre life by reducing the oxidation caused by oxygen. However, maintaining proper tyre pressure and regular rotation have a more significant impact on tyre life than the gas inside them.

In conclusion, while nitrogen tyres have certain benefits, regular air is still the more cost-effective and convenient choice for most drivers. Most automobile manufacturers agree that the benefits of nitrogen are not significant enough for the average driver to worry about.

When your engine light comes on, it indicates that your vehicle's onboard diagnostic system has detected a malfunction or irregularity within the engine or its related components. This could be something as simple as a loose gas cap, which can interfere with the fuel system's pressure, or more complex issues like a malfunctioning oxygen sensor, catalytic converter problems, or issues with the engine's ignition system. It's crucial not to ignore this warning. While the car might seem to run fine, ignoring the light can lead to more significant, potentially costly repairs down the line. The best course of action is to have your vehicle examined by a professional as soon as possible to diagnose and rectify the issue, thereby ensuring your car operates efficiently and safely.

Depending on the conditions. a tire with an H speed rating can reach speeds of 210 130 km/h mph under optimal conditions.
