Things to solve a cold start issue?

[PamelaAsistio]

Hi, just to give an update. Napa-change oil na po namin yung car yesterday and tune-up but still the car is having this cold start problem. When I start the engine this morning, it took 8 tries bago tuluyang umistart yung car. Ano pa po kaya ang dapat ipacheck, were beginning to loose hope, lagi na lang pong ganun, hinde magamit sa oras yung car cause I always need to allot more time sa umaga dahil nga po hinde agad umiistart. TIA

Nag-backread ako sir, and wala ako nabasa related sa air filter,
A clogged air filter may cause hard starting,
sabayan mo pa ng natuyong gasolina sa carb overnight,
and sabayan mo pa ng e10 gasoline na not designed for cars with carburator system
which makes it evaporate more.

Normal practice na these days with carb yung before cold start,
give your gas pedal a tap or two, pra lang mareplace yung natuyong gasolina
na nakareserve sa carb para pag crank mo, more likely didiretso start na sya.

Hindi ako nagbackread so baka na-suggest na din ito.

Check mo yung choke mechanism kung nagana. Kung manual choke mejo madali remedyohan. Pero kung electric choke, kelangan mo ng espeyalista. yung choke kasi isa sa mga overlooked system ng carb pero malaking tulong siya sa cold starts.

Sir, ok naman po ang air filter, nachecked na rin before.

This is really what I am doing everytime I start the car, actually, more than 2 pumps in gas pedal pa po ginagawa ko para lang umistart because 1 or 2 pumps will not do.

Sir, how do I distinguish if my carb is a manual choke or electric choke?

Nag back read ako pero baka na miss ko, ano gas pinapakarga mo dyan? Petron Blaze lang ang pwedeng gas sa mga carb na makina and older engines na nde ethanol compatible, ang problem ko lang ngayon sa Blaze is mas mahirap mag start ang kotse, this started a few months ago in my case sa lumang Ford Telstar namin at sa Honda Accord ko na parehong Blaze ang gamit. Dun sa accord bearable naman kasi EFI, nde nga lang 1 click start sa umaga pero pag nastart na at pinatay ulit madali na ulit ma start.

Ang problema ko yung telstar, madalas kelangan either naka choke or apak muna sa gas, minsan mga 2-3 tries bago mag start.

In my case both hard start problems when cold are due to the newer formulation of Blaze. Unfortunately nde naman ako pwede gumamit ng ibang gas kasi nga bawal ethanol baka madami pa masira.

Nag hanap hanap ako online, read similar problems sa BMW, Mitsu Galant at mga naka motor na Blaze ang gamit.

Binasa ko rin yung buong thread Ms Pamela, malaki laki na rin gastos nyo sa kakalipat lipat ng "duktor at ospital" so I agree with Manilablock, try nyo rin magpa diagnose sa casa, P500 fee lang and deductible naman if convinced kayo na ipagawa sa kanila.

Just to share, I now make it a point to buy parts and fluids for my old civic directly from Honda if there is no "reliable/branded" replacement available, but I have it installed outside. Iwas din ako sa unknown talyer na may nakalagay sa signage na "expert in..." pero marumi at makalat ang shop, walang lifters at professional tools and equipment ako na makita.

Maybe it is worth to invest more and have the repairs done in the casa.

have you check the carb choke machanism? why not check it manually? takpan mo ng kamay mo ang carb while starting it. pag mag start agad, choke ang problema mo. just give it a try.

Sir, normally pag choke mechanism ang issue ay inaadjust ang A/F mixture, right? Correct me if Im wrong, di ba ito po yung screw na may spring sa may carb aside from the idle up for RPM? Thanks

everybody seems to be concentrated on the fuel and the fuel system. how is the igntion? is the spark intensity high enough? are there secondary ignition leaks? if i am not mistaken, this engine has a distributor and spark plug wires. try running the engine and tune the radio to A.M. and listen to static at different radio frequency on this band. if there are high voltage leaks, there will be ticking noises heard on the radio speakers proportionate in frequency to the engine speed.

also check baka sa simpleng fuel filter lang eh di pa napapalitan, baka clogged na.

Sir, fyi :-)

Sir, our carb was just overhauled and replaced the complete repair kit by carb experts in kamuning last june only. They were also the one who handled our other car's carb, kaya trusted na po namin at tested na pulido ang gawa nila. Fuel filter is also new

aabot ba sa frequency band ng AM ung frequency ng high voltage peaks? ano pang ibang test na pwede gawin?

yes ma'am, i have used this trick for decades

Ano idling ng engine kapag normal ang andar? Try mo muna pataasan ng konti. Gawin muna 1,000 rpm for test isolation. Off mo na rin muna aircon every time mag cold start ka.

Sir, around 800 to 900 is my normal rpm. And yes, my a/c is always off everytime I start the car. Thanks

Madam, na suggest na ba ang grounding cables? just run a big gauge cable from batt neg to the engine block basically

[Chinoi]

Pa overhaul mo kaya yun Starter mo. P500 lang naman labor nun. Minsan kasi carbonized or madumi na motor commutator kaya mahina buwelo ng pag Start. Lilinisan lang iyun.. Pang isolate lang.

Palinisan na rin yun Ground wire sa casing ng Starter at mga electrical terminals.

[PamelaAsistio]

try mo paadjust yung screw na may spring na responsible for fuel-air mixture....diko alam ang tawag nun eh....alam na ng mekaniko ko yan....kung di niya pa magets, sabihin mo na, "YUNG INAADJUST NGA NA ONE O'CLOCK"..... pag di niya pa rin alam yun, cgurado, astronaut siya.... try mo lang mam...

have you check the carb choke machanism? why not check it manually? takpan mo ng kamay mo ang carb while starting it. pag mag start agad, choke ang problema mo. just give it a try.

Mga sirs, 2 questions lang po:
1) Normally pag choke mechanism ang issue ay inaadjust lang ang A/F mixture, right?
2) Di ba ito po yung screw na may spring sa left side ng carb cause the other identical screw beside thermowax valve is for the idle up naman, tama po?

Thanks
