When Fogging Oil Helps Storage and When It Packs Jets

A demonstration field guide for fogging that is over-applied into the venturi using visible oil in jets after storage before replacing the jets.

This demonstration guide answers one field question about fogging that is over-applied into the venturi. Measurements come before parts, and the notes are not a generic equipment FAQ.

Diagnose before replacing parts

Start with visible oil in jets after storage. That reading separates fogging that is over-applied into the venturi from adjacent faults that share the same complaint.

If the measurement is out of spec, treat the jets as the primary path. If it is in spec, do not replace the jets just to complete a parts list.

Repair the failed system

The usual correction is the jets, installed to the documented spec for this complaint.

A demonstration shop records the finding so the next technician is not repeating a guess about fogging that is over-applied into the venturi.

Stop before you make it worse

Do not fogging through the carburetor until it drips. That shortcut hides the original measurement and creates a second failure.

If the machine still fails after the jets is corrected, convert the visit to a broader diagnosis rather than stacking parts.
