problem in khyber when running on petrol
My car runs fine on CNG but when i switch to petrol it drives ok until I take my foot off the accelerator and the engine stops running so I have to start the car all over again ...
Coz of this I am driving on CNG howevr because thr is NOW a CNG shortage I want to get this looked at and fixed.
Any suggestions what this might be.... what should be done .... and approximate cost ?
This issue of yours can be as minor as choked fuel filter or inefficient fuel pump OR
it can be (most probably) blocked carburetor fuel lines and vacuum ports.
Get the system checked. Service the carburetor thoroughly from inside out with proper calibration of float and needle valve.
Set IG timing (without vacuum advance) to 15 degrees BTDC at 900RPM to avoid missing (Dieseling) on petrol without considerable loss of power on CNG.
Fuel Filter: 50/-
Stock mechanical Fuel Pump (Japanese): 2000/-
Carburetor service Labour: 500-1000/-
allrite .... I will taking the car in for repairs tomorrow ... lets see what comes of it
its slow jet problem .plz check the electronic slow jet cable .
instead of installing a japanese fuel pump in my khyber i installed mitsubishi electric fuel pump(1950rs new) and now my car is running good MA!mechanical pump gets useless in a year or later!
ok i got it checked the carbuerator needed cleaning and the 'fuel jet ?' was clogged so it was cleaned nw car running fine on petrol ... thnks guys fr ur advice and help

Khuda ka khauf karlo kuch. The guy needs help and you're advertising your own cr*p.
Please don't spend any money on fuel oil or others, just go to mechanic, open the fuel oil, open bonut and fuel pipe joining engine, pass heavy pressure air about 1, 2 minutes , and problem is solved.
The same problem is been to me , and i have spent 20 thousand to solve this but invain finally someboddy did this and that day was biggest and relaxed day of my life.
I have Khyber 97, car was running smoothly on CNG but when converted to petrol it is creating problem, i have changed carborater kit, fuel pump and filter as well, fuel tank is also clean but the problem is still there, car starts and runs but after some kilometers running it stops....really panic about the situation.....need advise..
