This demonstration guide answers one field question about a restricted jet or an inverter that cannot handle surge. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with loaded voltage and frequency at a known wattage. That reading separates a restricted jet or an inverter that cannot handle surge from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the carburetor jet or inverter board as the primary path. If it is in spec, do not replace the carburetor jet or inverter board just to complete a parts list.
Repair the failed system
The usual correction is the carburetor jet or inverter board, 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 restricted jet or an inverter that cannot handle surge.
Stop before you make it worse
Do not adding a larger generator without measuring actual surge. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the carburetor jet or inverter board is corrected, convert the visit to a broader diagnosis rather than stacking parts.
