Candles with burnt stems
Burnt filament rod (pic.), a consequence of a malfunction of the nozzle, and not the glow plugs. A similar malfunction, a lack of the inner, and not the outer, part of the candle. If such candles are found (arrow, fig.) it is not enough just to replace them, it is necessary to check the nozzles for spraying, noise, pressure, tightness (factory work). At the same time, pay special attention to the fact that the spray spot during sharp vigorous pitching (4-6 strokes/sec) was flawless.
