Kia Pride engine

[supermario]

---

Hello mga bros. A little help please.

I have one particular sparkplug (2nd one from the distributor) in my B3 Kia pride engine (carburator type) that gets busted very frequently. I remedy the problem by cleaning the electrode with sandpaper and it works only for a few hours until the engine gets cold again. So I would clean the electrodes early in the morning but it becomes "palyado" again in the afternooon on my way home. I noticed that there's a constant small spark in my ignition coil that would jump from the high tension cable (center) to the negative terminal of the ignition coil. My questions are-

1.) Is my ignition coil already busted ?
2.) Is the ignition coil the one damaging the sparkplug?

Technical experts, I need your help on these. Thank you.

Kung busted imong ignition coil, di na mo andar imong sakyanan kay di naman maka spark ang sparplugs.
Check that particular wire nga nag misfire basin naay putol or luag lang.
Di na basta ma damage ang spark plugs, kung nadamage na due to energy sa coil, hilis na unta imong spark plugs.
Ang imong problema karon misfire lang gyud, very common kung:
1. di mao ang fuel mixture
2. hinay ang spark due to resistance along the high voltage path
3. walay klaro nga connection sa imong wire


Assuming walay problema imong wires, to isolate a spark plug problem, exchange that spark plug with the other spark plugs that is working. kung mo misfire gihapon ang the same plug, mao nay problema nimo, basin misaka na ang resistance niya.
Make sure pareho ang spark plug gap ana niya with other working spark plugs nimo.

Bro vern, i think ur correct nga its not the coil. Ur explanation makes a lot of sense. I actually replaced that particular plug with different ones (some even with brandnew) but it fouls out easily while all the remaining three plugs are still ok even up to today. I think its true, it must be the cable. I'll go for addressing the cable problem this time. Thanks alot bro.

By the way, do you tighten up the adjustment screw on the carburator to allow more air to the mixture or loosen up?

[vernie]

Adjust your idle screw for a stable idle with no misfire. clockwise=closing, counterclockwise=opening. Air and fuel mixture is already metered using the idle screw, it's the throttle screw that adds more air or raise your idle rpm but it's not only air ang makasulod using the throttle screw, apil pud na ang gasoline. You can even close the throttle screw, counter clockwise to further lower the idle rpm.

ok great, tanx

Another thing bro. If i nearly fully close the throttle screw, how come the smoke from the muffler smells different? Mas baho?

[vernie]

Lisod na tubagon kung wala ta kahibalo sa setting nimo sa idle screw ug kahimtang sa ubang bahin sa sakyanan. Another cause sa baho kanang exhaust system nga naa nay nag pundo nga karaang mga hugaw nga kung mo init na ang exhaust temperature, mangalisngaw pud na. Kanang vent or breather sa imong engine nga connected sa imong air cleaner, limpyo ra ba? Ang imong PCV nga linya from your engine to your intake manifold, naay oil catch can or condensator? Mas maayo kung naa. Ang
carburetor mismo including sa may throttle, di ra man kaha na oily?

[vernie]

Another thing, ang andar sa makina, wala man kaha misfire karon? ilhan nimo kung naay misfire kay naay bakante sa andar or naay pititi ang buto sa exhaust. Bisan gamay lang nga mga pitipiti nga tingog, misfire na ug kana nga portion sa fuel-air mixture derecho na sa exhaust inig exhaust cycle mao nga baho.

I understand your point and I totally agree with you bro. The engine has to be clean. I'm not actually adept on car engines but i like to make hands on with it because its very interesting. It is also for that particular reason that I cannot totally relate to all the different engine parts that you mentioned. Rest assured I always take time to clean the different engine parts because i simply like doing it. This time i will try to include the engine parts that you mentioned. Thanks kaayo.
