This demonstration guide answers one field question about oil consumption under deck load or a rich carburetor. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with plug color after a loaded cut versus no-load idle. That reading separates oil consumption under deck load or a rich carburetor from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the rings or carburetor kit as indicated as the primary path. If it is in spec, do not replace the rings or carburetor kit as indicated just to complete a parts list.
Repair the failed system
The usual correction is the rings or carburetor kit as indicated, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about oil consumption under deck load or a rich carburetor.
Stop before you make it worse
Do not revving without load to "clear" the smoke. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the rings or carburetor kit as indicated is corrected, convert the visit to a broader diagnosis rather than stacking parts.
