Why It Matters
On the Type 4 engine you set ignition timing by lining the mark on the flywheel or pulley up with this scale. When the original scale is broken, painted over, missing after an engine rebuild or bent, you are guessing at timing. Wrong timing on an air-cooled Type 4 means pinging, poor power, overheating and burnt valves. A clean, readable scale makes a correct strobe timing check quick.
Installation Notes
- Fit the scale in the original position with the original screws and make sure it sits flat and does not touch moving parts.
- Confirm TDC on cylinder 1 before trusting any scale, especially after an engine rebuild or a flywheel change.
- Set timing to the spec on your engine's emissions decal or in the workshop manual for your engine code.
