Carborator Problem - Cold Start - nahihirapan

[earthlyken]

Hello mga fellows tsikoters..

Just wanna ask for some advise kung ano problem ng otobot ko..

i got Toyota Corolla 1.6GL na automatic, carborator pa siya...

nahihirapan ako mag start pag cold start, example, pag naka pahinga yung oto ko for about 5 hours and more...pag start ko..parang nalulunod siya na hirap na hirap mag rev or mag idle, pero pag tumatakbo na...ok na lahat..

pinalitan kona yung sparkplug, fuel filter at pina overhaul kona yung carborador ko...

i'm desperate, kasi nag tanong ako sa mga mekaniko, sabi nila, baka fuel pump daw (e pag tumakbo ok na e, pati yung hatak), sabi naman yung isa baka barado daw carborador ko (e kaka overhaul lang)

any advise will be greatly appreaciated...thanks for the time in reading these..

Thank you in advance...

You have just burn so much money to fix this problem but havent prevail, yet since all the changes and carburator overhauling this should bring your car in great shape!

Perhaps, not yet! The problem still there and disperately seeking help. Of course you dont want to burn a chunk of money to those money hungry mechanics and hear diff. story if they cant bring your car properly.

earthlykin, I was thinking the Cold Start Valve but not possible since this a carburated car. The only thing I can think of is your ignition system. You have changed the spark plug , overhauling your carburator but you havent change your Cap and Rotor and check also your spark plug wires for crack replaced it if nescessary. Check also your fuel pump relay if corroded, clean it or replace it. Good luck.

will do that, thank you very much for the input..

for other information, please kindly post your advise so that i can try it if these procedure won't work out for me...

Thank you again for reading...

ignition coil chek mo bro.... or wiring mo....

ussually kasi ako pag nag drive ng d carburator i click it twice then turn it of ule tas click the key twice again chaka ko tnutoly mag start para pasok n ung mga kuryente! ewan ko lng kung it works for ur car...

I would presume that your car is nearly a decade old....as such pede yung coil, high tension wire, vacuum advancer and carburator ang culprit.

It is kinda weird kasi - "nalulunod" - check if you see fuel flooding sa carburator area pag-nagstart ka at ayaw mag-start. If this is the case, try to start the car without stepping on the gas pedal.

Mayroon pa bang manual "choke" yung carburator mo? My oldschool car have this... so for a one click start, I choke the carb muna, pagka-start atsaka ko i-rerelease and choke slowly, taking note of the idling.

Yung naidrive ko na corolla dati na 2E carb engine (not a 4AGE like yours) have an "automatic" choke mechanism when you start it....since mechanical ito, merun tendency na magwear down ito.

Ignition timing perhaps?

[groucho]

I agree. If the carb is clean, then check the electrical/ignition system.

+1 on this.

based on your avatar, you have a corolla ae92. most models has manual choke (im not sure sa mga automatic, rare ksi ae92 na automatic), nasa left side just below the steering wheel. yung parang button na hihilahin mo.

pag cold start, depress pedal for 2 seconds then pull the choke and then start the engine. after around 30 seconds slowly ibalik mo na yung choke.

[earthlyken]

Thank you guys for all the advise..

as you mention about the manual choke, sa otobot ko po, may automatic motor choke siya naka dikit lang sa carb mismo, kulay itim siya..medyo buhol buhol na yung mga wiring niya, pero gumagana pa (sinubukan kong tangalin habang naka start yung makina, pag tangal ko namatay yung makina, so it means that gumagana pa siya..) sabi naman ng mekaniko ng dad ko ay baka sira nadaw yung motor choke ko na kailangan kona palitan..

napag isip isipan konadin na kung ano mga possible problem..

1.) battery - ok naman ang start
2.) fuel filter - bagong palit
3.) fuel pump - pag tumatakbo na, ok na lahat
4.) carbs naman - bagong overhaul

gusto ko na nga ibenta to eh..kaso lang 1st car ko..kaya kahit papano alaga padin..hinde naman ganyan dati to eh..lastweek lang nagsimula..

Any other advise you can give me will be surely appreciated..

Thanks for reading these..

bro ung charade ko ganito din dati. AFAIK ganun tlaga mga carb engine. sa una mababa menor tapos tataas. sa efi naman baligtad. sa una mataas menor nya tapos kapag normal na ung temp. bababa na ang menor. so ibig sabihin walang sira oto mo

ganito kasi yun po, pag start ko, 1 click lang..then shempre pag start ng engine medyo nakatapag ako sa gas pedal, pero pag binitawan kona, parang hirap yung engine at mamamatay siya..

pag rev naman ako ng rev, panget yung tunog niya...parang bumubula yung muffler niya...pero pag nag idle na siya..ok na lahat..

Thanks,

afaik, this is not necessarily true. carbureted engines have fast idle during cold starts. like in 4AF engines, fast idle should be like 3000rpm. then after a while, the rpm returns to normal.

check mo yung choke before a cold start. dapat closed siya para rich yung fuel mixture. mag open din siya after mo ma start yung engine.

pano ko po malalaman kung open or close yung choke ko?

sorry kinda new of these stuff...sensya na kung medyo stupid mga question ko..

[wildthing]

open the filter housing/cover... close yun pag sarado ang throttle with the "butterflies".

Choking means no air (or limited air) so pagsinara mo ang butterflies machochoke un.

[zelenzo]

ganyan din prob ko sa oto ko, pag cold start sobra baba rpm tapos parang mamamatay pero pag nagtagal naman o naginit na makina o kaya tumakbo na ok na ung rpm nya, last week lng ko nagpatune-up, nakita prob ng mekaniko pag on ko ng aircon sobra bumaba rpm un pla di gumagana ung actuator valve switch kaya pinalitan nya ok na naman kaso ang problema ko ngyn e pag coldstart klangan mo pa antay ilang minuto o kaya itakbo na bago magstable rpm/idle nya..

[bomboklat]

try mo pre i adjust yung turnilio sa baba ng carb mo kung meron yan,bali malapit sya sa hose ng tubig galing ng water pump,pa clock wise ang ikot

[earthlyken]

ok na otobot ko sa wakas...

the problem was the automatic choke..may konting kalawang sa loob niya...kinalkal kolang at spray ng WD40 then brush with toothbrush tapos kinabit ko..ayun..swabeng swabe na siya..

Salamat mga repapips...
