Common Issues It Can Address

• Vacuum leak at the distributor advance unit
• Rough throttle response caused by worn advance components
• Timing instability on classic GM distributor systems
• Restoration needs for original-style ignition service

Installation Notes and Tips

Verify distributor number and emissions calibration before ordering, since fitment varies by year, engine setup, and emissions package. Match the vacuum advance to the original distributor application and confirm the hose connector orientation before installation. After replacement, set ignition timing to specification and check engine performance at idle and under light throttle.
