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

[smijaz]

ok ill check all things you said in coming wek cuz ive got exams this week.
one thing,i strted the car,and then put hand on the air cleaner assembly pipe to stop any air going in,the car rpm dropped to very low but car didnt go off on PETROL,while doin same on cng caused the car to shut off at once..is it supposed to happen like this?or car is taking some air from else where?? then i also tried without the air filter assembly,i closed mouth of carb with hand and car went straight off on petrol and cng!

It is obviously taking air from somewhere in the air filter container. Check two lid rubber rings and carburetor mouth ring.

oka..ill check it..but why on cng it goes off immediately? but on petrol,it dont...

I am facing an issue with my ride for a couple of days now.
The issue is car starts to vibrate at 50-60km/h speed till 80km/h and smooths down above it. The vibration is gone as soon as i take my foot off the accelerator or push it hard to get out of the vibration zone.
Cant locate the source of it but its felt in the whole car and is quite severe.

I have checked the following

1. engine & gear mounting are good.
2. Alignment is OK.
3. All tyres are balanced (front ones are new)
4. balancing rod bushes are new

Status of following is unkown
1. CV joints (They dont make any noise)
2. chimta and its bushes
3. tie rod ends

What is the possible cause of this problem

Thanx

Problem Solved.
But the cause was multiple issues

Chimta's were worn out completely
Tie rod ends were loose
Inner CV joint had no grease (boots were intact but with time the grease dried up)
Left wheel balance was out by 15 points

So
New chimta set, new tie rods ends, balancing rod bushes, grease for the inner CV joint, wheel balancing all wheels and alignment.

Bought a few tools for DIYs required by my old but loyal ride

One of those tools is a compression tester

After engine warm up the Dry CT results were as follows

Cylinder #1: 172
Cylinder #2: 172
Cylinder #3: 172

The results are a bit on the lower normal side but atleast there is no difference among the results. therefore i didnt went for the wet test

For a long time I was trying to get these tools for the maintenance and trouble shooting of my ride in a proper by the book manner.

And finally I have got them all in a day. I am happy man today.

A torque wrench (20 lb-ft to 150 lb-ft) made in taiwan

A universal type compression tester

Trisco inductive timing gun with Xenon light

And a UNI-T (UT33-C) multimeter with temp sensor

[smijaz]

Getting my hands dirty on the weekend and checking the HT wire for resistance

the result is as under

332ohms.

Plug wires are of different lengths so reading differed, they showed 403ohm, 380ohm and 350ohms.

great tools, just one little brotherly advice, never ever drop that torque limiter ratchet, handle it like glass and always reset it back to zero after every use.

Thanks.
PMed U , these tools are easily available at few specialized dealers at Brandreth Road (Lahore) with huge price differences so it is advisable to check from a couple of shops before buying.

Nice tools. I wish i had them too. Please let me have an idea of prices. If i went to check out, i will have a price reference.

About the resistance of HT wires,


the value is in kilo-ohms...

Which wires are you using?

the smell at the station could be the gas pressure relief of the filling nozzle. On removing the nozzle, the gas pressure in the filling hose is relieved with a noise. You may be smelling that.

Some times there is a leak in car. When fill from a station where pressure is higher or full, you may smell the leak.

Agreed.
