This demonstration guide answers one field question about a limiter that cuts spark at a lower rpm than expected. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with rpm at breakup versus the documented ceiling. That reading separates a limiter that cuts spark at a lower rpm than expected from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the limiter module as the primary path. If it is in spec, do not replace the limiter module just to complete a parts list.
Repair the failed system
The usual correction is the limiter module, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a limiter that cuts spark at a lower rpm than expected.
Stop before you make it worse
Do not removing a limiter to "get more cut speed". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the limiter module is corrected, convert the visit to a broader diagnosis rather than stacking parts.
