Self Tunning - Khyber G-10 (Plugs, valve clearance, spark gap etc)

[smijaz]

AoA

i am facing a problem which i have been unable to diagnose.

The problem is a "Hichki" (some time one and sometime in pair) which occurs under no specific condition like RPM, load, gear etc.
I have done the following DIYs tappet (inlet 0.006'', outlet 0.008'' at cold engine), plug gap 0.80mm, distributor signal generator air gap 0.008", swapped the plug wires and distributor with other ones, adjusted the CNG mixture but nothing, the hitchki can occur at any time and is gone with out any trace.

It feels like the car engine is turned off for a sec and then comes to life again.

I am planning to visit pindi/islamabad at the weekend and am concerned about this issue, as this may get me in to trouble on the motorway.

plz guys help me out here

^ Dont have much info regarding your issue.
BTW When are you coming to Rawalpindi?
Saturday?
We can have a Khyber meet.

yes bro, Saturday was the programme.

wish me luck to resolve this issue, because if its electrical it can get be stranded in the middle of no where at any time.
so, if it stays then i am gonna take a bus

^ Hmmm,
Yeah you are right,
I was having this jerking kind of issue and after the changing of plug wires, plugs the problem was still there.
Finally it got solved by putting a resistance with the igination coil and my mechanic told me that it was the extra current that was responsible for this jerking.
I dont know that what is the cause of these jerks in your case so cannot say much.
You should consult your mechanic and lets see what does he says.

[smijaz]

thanks @Daniyal
You may be right about the resistance as i am not using any, i will try that tomorrow.

lets see what Mr. xulfiqar has to say on my problem, I am counting on it

its nice to see PW people following good car upkeep - after installing the T-stat you'll notice after about 3 oil changes how clean the oil is - colder engines form heavy sludge with water condensation etc. You will also notice that your oils even after 5000 kms will be good for use.

As for the hitchki thing - to me it seems as if you are losing ignition power to the ignition coil - as you say it seems that the engine shuts off for a moment - (maybe a bad ignition switch or wiring from the steering column) - or pretty simply your coils resistance has decreased and the ignitor has a hard time switching it off - or the ignitor is feeble and old - checking the ignition coil and putting a resistance on the positive would help in this case

thanks, I will follow your diagnostic pattern and hope will find something.

About the igniter , there is a black plastic cover on the ignitor in the distributor but in my case the black cover is gone, can that be the reason.

oh..so u comin to pindi..
good to knw,do let me knw if ther comes a khyber meet..
about tht hitcki,smijaz bhai y not try alto dry coil n then see.it wud cost not more than 600 for kabli one..
kisi frnd ke utar k try kro,if it solves prob,then go n buy urself a used one,warna frnd ko wapis kr do n get ur coil back..
it gotta b electrical issue rather than mechanical..
carb ganda tou nae???

[cracked]

n on soft note,khyber aisi gari Q hy jis ko hiccups,sneezes etc lagi he rahti hain..
log kahty thy strong car hy but ye to bari FEMALE type nazuk car hy..LOL

yeah, its making me wonder too, LOLz

[cracked]

sure...try krna..
aik dosry ke khyber he dekh laen gy k kis my kia kia chez SAHI hy..LOL
mainy saturday ko tappets b adjust krny hain khud..hope ho jaen,
lol

you mean that the black disc shaped distributor shroud is missing? - that alone can cause misfires as the spark current can ground to the distributor internals easily (rotor is not that far)

yes sir thats exactly what I meant and was afraid that it might be important when i lost it while cleaning and oiling the timing advancer bearing.

So now where to get that peace of plastic:S

[ahsanonline]

kabari bazaar!!! thats where you're headed mate!

xulfiqar bhai, plz tell me how much of a difference a new distributor cap would make? the metal stumps on the inside of my current distro cap are okay-ish. no rust, but they seem to have gone whitish or something...car does misfire, seems that one single cylinder is misfiring....

[Xulfiqar]

can make a huge difference if it starts to leak current, dont tell me that you have tried cleaning it and the rotor with sandpaper.

you can clean the white crud with a thin screwdriver, just be careful not to scratch the plastic, that can cause tracks and leak current - also check the valve clearances on the cylinder thats misfiring

[Xulfiqar]

did you O/H the dissy - that bearing plate inside the dissy is supposed to have a slight drag - the centrifugal advance weights should be lubed up nice and the shaft greased up real good

[daniyalahmad]

oh..so u comin to pindi..
good to knw,do let me knw if ther comes a khyber meet..

If the plan is finalized then I,ll contact you to decide the place and time of the meet.
We can invite other Khyber owners too.

Mausam change ho raha hai na.

@smijaz
Do update us with the position of your car.

[smijaz]

the bearing plate inside the distributor was sticking some time at advance position or sometime does not respond to suction.

therefore i opened it up and washed it with WD40 and greased it. Now its working with the suction and comes back when released.

I didnt oiled or greased the shaft and the weights, will do as per your instruction

[cracked]

ye kia alien talkin ho re hy..
wat baring inside the ditributor?
wat wheight?
wat O/H?
wat shaft?
wat suction?

hum nalaiqooo ka b khyayal rakah kro g:p
lol
