This demonstration guide answers one field question about points that pit and change timing. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with point gap and dwell where documented. That reading separates points that pit and change timing from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the points as the primary path. If it is in spec, do not replace the points just to complete a parts list.
Repair the failed system
The usual correction is the points, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about points that pit and change timing.
Stop before you make it worse
Do not filing points until the rubbing block is gone. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the points is corrected, convert the visit to a broader diagnosis rather than stacking parts.
