Mehran car is giving black smoke on petrol ? On CNG everything is perfect on smoke or anything .. my question is what would be problem on petrol ???
Bro,Get your car carburetor adjust from a good mechanic. it requires only good tune up. Black Smoke is due to UN-burned Petrol.
Drinking too much petrol due to bad carb. Get the carb serviced. May need to change some jets.
carb is running rich-get it overhauled
Thanks guys ....
