Walang adjustment for rough/smooth idling. Meron adjustment to increase/decrease idle speed. Yan yung screw na nakabangga sa throttle lever sa taas ng injection pump. Turn in adjusting screw to increase idle, turn out screw to lower idle speed.

Hi dieseldude, ask ko sir. Kakapalit ko lang ng nozzle tips ng pajero 4M40 ko. Pansin ko pag umaga pag ka start ko,gryish white ang usok compared before with my old nozzle tips na hindi halata. Pero after a while of warming up humuhina naman yung grayish-white smoke nya. Is this normal? Pareho naman 129 yung nozzle tip na kinabet...

Another is, me effect ba yung washer na kinakabit or nailalagay sa mounting hole ng nozzle tip?

I hope you can shed light on my query. Thanks

Pero after a while of warming up humuhina naman yung grayish-white smoke nya. Is this normal? Normal yan sa old engines na medyo mababa na ang compression. Nag iimprove ang compression pag uminit na ang engine.

Pareho naman 129 yung nozzle tip na kinabet... Original Zexel nozzles ba ang nilagay mo? Tama ba ang opening pressure?

Another is, me effect ba yung washer na kinakabit or nailalagay sa mounting hole ng nozzle tip? Meron effect kung sobra ang thickness ng compression washer.

I hope you can shed light on my query. Thanks

Sa Bosch Malabon diesel ko pinapalitan sir yung nozzle tips ko yun kasi malapet samen. Anu effect sir ng thickness ng compression washer especially on my 4m40? Goal ko kasi maimprove yung FC ng Pajero ko...

May relasyon ang gasket thickness sa compression. Ano sabi ng Malabon diesel?

Compression washer nga sir yung culprit. Replaced all four Big and all four small, plus 4 return washer. Good as new na sya... Thanks

White smoke from cold start CB, tpos me fuel knock pag arangkada. Di maganda yung lapat ng compression washer. Inayos naman nila under warranty. Ok naman na ngaun. Pinapalitan ko lang, gusto ko kasi tumipid nalalakas kasi ako sa fc nya. Turned out wala na sa standard values yung nozzle tips ko...
