Sumec SV200 Operator's Manual

The Sumec SV200 engine typically uses timing marks on the flywheel and the engine block to set the correct ignition timing. These marks are usually small notches or lines stamped into the edge of the flywheel and aligned with a fixed pointer or reference mark on the engine casing.

To locate the timing marks on the Sumec SV200:

1. Remove the flywheel cover: This gives you access to the flywheel.
2. Rotate the flywheel: Turn it manually until you see a notch or line on the flywheel edge.
3. Look for “T” or “F” marks:
- “T” usually indicates Top Dead Center (TDC) of the piston.
- “F” indicates the ideal point for ignition firing.
4. Align the timing mark: Use the reference pointer on the engine block to align with the “T” or “F” mark as needed for timing adjustment.

Exact positions may vary, so refer to manufacturer specifications for precise timing degrees before TDC.
