Setting points without a dwell meter might seem daunting, but it’s an essential skill for anyone who wants to work on classic cars or vintage engines. A dwell meter is a tool that measures the amount of time the points are closed during each cycle, which is necessary to ensure that the engine runs smoothly. However, not everyone has access to a dwell meter, and some might not know how to use it properly. Fortunately, setting points without a dwell meter is possible with the right tools and technique. In this article, we’ll share how to set points without a dwell meter.

What are Points, and Why Are They Important?
Points are an essential component of an engine’s ignition system, responsible for opening and closing the circuit that generates the spark necessary to ignite the fuel and air mixture in the combustion chamber. They are usually made of tungsten and are subjected to wear and tear, which affects their performance.
Points’ proper functioning is crucial for engine performance and fuel economy. Faulty points can cause the engine to misfire, stall, or even fail to start. It can also lead to increased emissions and decreased fuel efficiency.
How to Set Points Without a Dwell Meter
First, you have to gather all the necessary tools. To set points without a dwell meter, you will need the following tools:
Feeler Gauge: A feeler gauge is a tool used to measure the gap between the points. It consists of a set of thin metal blades of different thicknesses, usually in a holder, and has markings indicating the thickness of each blade.
Timing Light: A timing light is used to adjust the engine’s timing, which is related to setting the points’ gap. It is a handheld device that illuminates the timing marks on the engine’s crankshaft pulley or flywheel, allowing you to set the timing accurately.
Screwdriver: A screwdriver is used to adjust the points’ gap. It should have a flat blade that fits the screw holding the points’ stationary part.
Small wrenches: Small wrenches may be necessary to adjust the distributor, which can affect the timing and points’ gap.
Step-by-Step Guide to Set Points without a Dwell Meter
Now that you have the necessary tools, follow these steps to set points without a dwell meter:
Locate the points: The points are usually located inside the distributor. Refer to your engine’s manual to find out the exact location.
Remove the distributor cap: To access the points, you need to remove the distributor cap. Be careful not to damage any wires or connections.
Identify the parts of the points: The points consist of two parts: the stationary part and the movable part. The stationary part is held in place by a screw, while the movable part is connected to a spring.
Rotate the engine: Rotate the engine until the points are fully open. You can do this by turning the crankshaft pulley or using a remote starter.
Measure the gap: Insert the appropriate feeler gauge blade between the points and adjust the gap by turning the screw with a screwdriver until it is the correct thickness.
Check the timing: Use a timing light to check the timing while adjusting the points’ gap. Adjust the distributor if necessary to achieve the correct timing.
Reassemble: Once the points are set, reassemble the distributor cap and any other parts you may have removed.
Tips and Tricks for Setting Points without a Dwell Meter
Here are some tips and tricks to help you set points without a dwell meter:
- Make sure the engine is at operating temperature before setting the points.
- Clean the points with fine sandpaper or emery cloth to remove any corrosion or buildup that could affect their performance.
- Use a timing light to check the timing as you adjust the points. This will ensure that the engine is timed correctly and will run smoothly.
- Use the appropriate feeler gauge blade for your engine’s specifications. Refer to your engine’s manual for the correct gap size.
- If you’re unsure about the timing or the points’ gap, consult an expert or refer to your engine’s manual.
- Double-check your work after reassembling the distributor cap and any other parts you removed. Make sure everything is securely fastened and connected.
Frequently Asked Questions
Here are some FAQs about setting up points without a dwell meter –
Q: How often should I check and set the points?
A: The frequency of checking and setting the points depends on the engine’s make and model. Refer to your engine’s manual for the recommended interval.
Q: What is the correct gap size for my engine’s points?
A: The correct gap size for your engine’s points depends on the make and model. Refer to your engine’s manual for the correct gap size.
Q: Can I use a feeler gauge to check the timing?
A: No, a feeler gauge is used to measure the points’ gap, not the timing. Use a timing light to check the timing.
Q: How do I know if my points are faulty?
A: Faulty points can cause the engine to misfire, stall, or even fail to start. If you notice any of these symptoms, it’s a good idea to check the points and replace them if necessary.
Q: Can I set the points without removing the distributor cap?
A: No, you need to remove the distributor cap to access the points.
Q: Can I set the points without rotating the engine?
A: No, you need to rotate the engine to set the points properly.
Q: Can I set the points without a timing light?
A: While it’s possible to set the points without a timing light, using one will ensure that the engine is timed correctly and will run smoothly.
