Ignition Contact Set Guide for the 1929 Franklin Model 137
Keep your classic Franklin's air-cooled engine running smoothly with a reliable new ignition contact set.
- The ignition contact set (points) is a critical wear item on your Franklin's vintage ignition system.
- Symptoms of failure include hard starting, rough idle, misfiring, and eventual no-start conditions.
- Since OEM parts are unavailable, a new aftermarket set from a reputable brand like Standard Ignition is the recommended replacement.
- Proper installation requires setting the point gap with a feeler gauge for correct engine timing.
Understanding the Ignition Contact Set in Your Franklin
For a classic vehicle like the 1929 Franklin Model 137, the ignition system is a fully mechanical and electrical setup. The ignition contact set, or points, is a primary wear item in this system. Over time, the constant opening and closing causes the contact surfaces to wear down, pit, or burn. A companion part, the condenser, helps prevent the points from arcing and burning out too quickly. Regular inspection and replacement of the points are essential tune-up procedures to ensure your vintage engine starts easily and runs without issue.
Symptoms of a Failing Ignition Contact Set
When the ignition points start to fail, your Franklin will give you clear signs. Because the points control the spark, worn contacts can lead to inconsistent or weak spark delivery. You might notice the engine is hard to start, or it turns over but won't fire up. Other common symptoms include a rough idle, engine misfires, stalling at low speeds, and a general lack of power during acceleration. These issues often get worse as the points continue to degrade, eventually leading to a no-start condition.
Can I still drive with failing points?
It is not recommended. While the car may still run for a short time with worn points, the performance will be poor and unreliable. You risk stalling in traffic or being stranded when the engine refuses to start at all.
Choosing the Right Aftermarket Part
For a 1929 vehicle, finding original "OEM" parts is nearly impossible. The Franklin Automobile Company closed in 1934, so new old stock (NOS) parts are exceedingly rare. Fortunately, the aftermarket provides reliable solutions. Standard Ignition is a long-established brand known for making quality ignition components for a wide range of vehicles, including vintage American applications. For the Model 137, a new aftermarket contact set from a reputable manufacturer like Standard Ignition is the best and often only choice to keep your car on the road. Modern manufacturing can sometimes offer more consistent quality than parts produced decades ago.

Installation Tip
Replacing ignition points is a classic tune-up task. While straightforward for those familiar with vintage ignitions, it requires precision. The gap between the points must be set correctly using a feeler gauge. An incorrect gap will affect engine timing and performance. It's also highly recommended to replace the condenser at the same time as the points.
Frequently Asked Questions (FAQ)
How often do I need to replace the ignition points?
For vintage cars, ignition points are a regular maintenance item. They can last around 20,000 miles, but it's good practice to inspect them during your annual tune-up. Given the age of the vehicle, checking them more frequently is a wise precaution.
Are modern aftermarket points better than the originals?
While original parts have a certain appeal, the quality of modern replacement points from a trusted brand like Standard Ignition is generally very reliable. The quality of currently available points can vary, so choosing a well-known brand is important for durability.
Do I need special tools to replace the ignition contact set?
Yes, you will need basic hand tools to access the distributor, a screwdriver to replace the points, and a feeler gauge to set the point gap correctly. Some mechanics also use a dwell meter to fine-tune the setting for optimal performance.
