Aircraft Spruce E25 Timing Indicator User Manual
How to Use the Timing Indicator E25?
Step-by-Step Instructions:
- Remove Spark Plugs: Take out all top spark plugs and install the piston stop in the No. 1 cylinder’s spark plug hole.
- Attach the Timing Disc: Secure the timing disc to the aircraft propeller spinner using the supplied rubber bands.
- Confirm Top Center:
- Observe the reading on the disc and adjust it to the exact midpoint of the degrees toward the T.C. mark.
- Remove the piston stop and confirm the compression stroke by feeling the air release from the spark plug hole.
- Set Magneto Timing:
- Move the propeller slightly past the required magneto timing setting.
- Ensure breaker points start opening at this position (checked using an Eastern Model E-50 Synchronizer).
- You have now found top center on the compression stroke.
- The breaker points should just be starting to open at this setting.

Troubleshooting Guide
Issue: Incorrect Timing Readings
- Solution: Recheck the piston stop positioning and confirm the pointer is accurately aligned with the T.C. mark.

Issue: Propeller Rotation Not Smooth
- Solution: Verify that the piston stop is not obstructing movement.
Setting the Magneto Timing
What is the engine indicator used to determine?
An engine indicator is used to determine mean effective pressure (MEP)and indicated horse power(IHP).
How does a speed indicator work?
An air speed indicator (ASI) is a device for measuring the forward speed of the aircraft.
Which indicator has high accuracy?
The Moving Average Convergence Divergence (MACD) indicator
Why should we use indicators?
Indicators inform other drivers what you want to do so they can make adjustments accordingly.
What indicator is the most accurate?
RSI and Bollinger Bands. proved to be the most reliable indicators, consistently delivering high win rates across both testing periods
Which indicator is most common?
Litmus indicator solution turns red in acidic solutions and blue in alkaline solutions.
What is the simple definition of indicator?
An indicator is a measurement or value which gives you an idea of what something is like.
