Rite-System Basic Magneto Ignition Timing Kit

Also included is a TDC locator pin, whose durable Nylon material won't harm the engine cylinder or piston. All of this is stored in a rugged aluminum case with a rigid foam insert for organization and protection during transportation or when you're using your kit out in the field. Both tools come with a lifetime free replacement warranty. The digital indicators are serialized and come with a 6 month replacement warranty.

1. Remove the upper spark plug of all cylinders.
2. Rotate propeller by hand until the #1 cylinder is on the "compression stroke."
3. Insert TDC Locator Pin into the spark plug hole until fully seated against the cylinder.
4. With one hand on the TDC Locator Pin, continue rotating the propeller by hand until you feel the #1 piston contact the TDC Locator Pin.
5. Remove the TDC Locator Pin from the cylinder.
6. Install the Mag-Rite tool onto the propeller spinner with the supplied bungees and insert the Digital Indicator.
7. Press the "ON" button and then press the "ZERO" button (0.0 will be indicated.)
8. Continue rotating the propeller by hand in the same direction until the #1 piston is past the TDC and moves back down the cylinder on the "power stroke," approximately 2 inches.
9. Insert the TDC Locator Pin into the spark plug hole until fully sealed against the cylinder.
10. With one hand on the TDC Locator Pin, rotate the propeller by hand in the opposite direction (moving the piston back toward the TDC) until you feel the #1 piston contact the TDC Locator Pin. 11. Remove the TDC Locator Pin from the cylinder.
12. Observe the reading on the Digital Indicator (half of this number is the TDC of the #1 piston.)
13. Continue rotating the propeller by hand in the same direction until the Digital Indicator reads half of the original number. (If the original number was 20.0, then rotate the propeller until 10.0 is indicated.)
14. This is the TDC of the #1 piston. Press the "ZERO" button (0.0 will be indicated).
15. Continue to rotate the propeller until the manufacturer's correct "Before TDC" reading is indicated.
16. You are now ready to install and/or time the engine magnetos!

Instructions for using the Fly-Rite:

1. Set the flight control to be adjusted to the "NEUTRAL" position per the aircraft manufacturer's instructions.
2. Install the digital indicator into the Fly-Rite tool.
3. Press the "ON" button and place the Fly-Rite tool onto the control surface.
4. Press the "ZERO" button (0.0 will be indicated).
5. Move the flight control to its fully deflected position in both directions and note the angle indication on the Fly-Rite tool in each position.
6. Compare these readings to the manufacturer's requirements.
7. If angle readings are not within tolerance, then adjust the flight control system per the manufacturer's instructions.
