QUES): - when I drive my car (suzuki mehran) on CNG, it doesn't takes out problem but I drives it on PETROL it starts missing. It does not resolve even after the tuning of carburetor. Please guide me what is this problem.
Check the spark plug gapping. Have the carburettor serviced.

I had same problem I changed filter, clean point, check fuel pump and carburettor but to no use then I cleaned the fuel tank from a Mechanic but after 2 days same problem then we cleaned the FUEL TANK at home using toilet TAZAAAB (careful) and did it 2 to 3 times and regularly check the FUEL FILTER for kachra and also open and clean carburettor and point (after 1 or 2 days there will be kachra after cleaning the tank in it) My 2007 mehran had solved the missing problem (Advise: Mechanic wont clean the TANK properly)
