I have a Suzuki Bolan 2010 model running on Petrol and CNG. As far as CNG is concerned, it controles the delivery of gas by the vacume created by the engine. But how the carburetor controls the flow of petrol?
Regards and thanks in advance for the help.

Well, before posting here my question, I have already surffed these sites. But, I could not find the answer to the question that is fuel flow is controlled, Is it with the vacume or with some sort of needle, etc or both?
the carburettor also works with the negative pressure (vacuum) applied by the engine on the intake stroke. The metering is controlled by a needle, its the oldest style of carburettors, and your bolan has a small throat carb best combination for low down torque.
It means, how much fuel is needed by the engine is controlled by the vacuum generated by the it in the carborator.
Thanks for help!
I have talked to a auto mechanic and he says that there is needle valve in the carburater to control flow of the petrol.
Any comments plz.
