New Ignition Points are installed Ignition Point Break-In and Maintenance Tips

New ignition points often experience a short “break-in” period as the rubbing block wears slightly and the contact surfaces seat themselves. Proper distributor cam lubrication is essential to minimize rubbing block wear and maintain stable dwell settings. Because of this initial wear-in period, ignition points should be checked shortly after installation.

If the ignition point gap is not rechecked and adjusted, the gap will usually decrease slightly. A smaller point gap causes the points to open later, which retards ignition timing.

Common symptoms of retarded ignition timing include:

• Idle quality changes
• Rough drivability
• Reduced power
• Sluggish throttle response
• Poor fuel economy
• Preventing Timing Drift After Installation

After installing a new set of points:

• Run the engine for approximately 30–60 minutes or drive the vehicle for up to 100 miles.
• Recheck and adjust dwell and ignition timing afterward.
• Always refer to your vehicle’s workshop manual for correct dwell and timing specifications.

Recommended Maintenance:

• Inspect/check ignition points every 3,000 miles.
• Adjust dwell/point gap as needed every 3,000–6,000 miles.
• Replace points and condenser approximately every 10,000–12,000 miles.
• Check dwell at every oil change.
• Carry a spare set of points and condenser in the vehicle.
• Keep a small screwdriver and feeler gauge in the tool roll for roadside adjustments.
