This demonstration guide answers one field question about idle set above clutch engagement. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with idle rpm versus clutch-in rpm. That reading separates idle set above clutch engagement from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the idle screw and clutch as the primary path. If it is in spec, do not replace the idle screw and clutch just to complete a parts list.
Repair the failed system
The usual correction is the idle screw and clutch, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about idle set above clutch engagement.
Stop before you make it worse
Do not raising idle to mask a low-speed jet fault. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the idle screw and clutch is corrected, convert the visit to a broader diagnosis rather than stacking parts.
