Advanced Timing Keys

What Are Timing Keys?

Timing keys are offset keys that replace the stock flywheel key. They rotate the flywheel (and thus the magneto) relative to the crankshaft, advancing the ignition timing.

Common timing key degrees:

• 0° Key: Stock timing (no change)
• 2° Key: Mild advance, safe for most builds
• 4° Key: Moderate advance, requires billet flywheel for high RPM
• 6° Key: Aggressive advance, requires billet flywheel and billet rod

Installation Requirements

Installing a timing key requires:

• Flywheel puller tool
• Torque wrench (to properly torque flywheel nut)
• Impact gun or breaker bar (for flywheel removal)
• Socket set

Important: Always use a torque wrench to tighten the flywheel nut to specification (typically 50 ft-lb for Predator 212). Never reuse the stock key—always use a new timing key.
