This demonstration guide answers one field question about worn governor gear or a stretched linkage. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with linkage free play at idle and wide-open throttle. That reading separates worn governor gear or a stretched linkage from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the governor linkage and spring as the primary path. If it is in spec, do not replace the governor linkage and spring just to complete a parts list.
Repair the failed system
The usual correction is the governor linkage and spring, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about worn governor gear or a stretched linkage.
Stop before you make it worse
Do not bending the governor arm to raise idle permanently. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the governor linkage and spring is corrected, convert the visit to a broader diagnosis rather than stacking parts.
