How to Use
- Rotate the flywheel by hand to confirm it moves freely and smoothly.
- Check that all sliding parts are clean and unobstructed.
- Fill the alcohol lamp to no more than two-thirds capacity using 95%+ isopropyl or ethyl alcohol.
- Place the lit alcohol lamp beneath the front end of the test tube.
- After approximately 1 minute of warm-up, give the flywheel a gentle spin — the engine will begin running on its own!
- Note: When the alternator is attached, allow slightly longer warm-up time before spinning.
⚠️ Safety Notice: The heated test tube and connected metal parts become very hot during operation. Do not touch these components while the engine is running or immediately after use.
