sharp,

Ok with the carby it does not really suck the fuel from the tank you require the fuel from the tank to be flowing to the carby otherwise the machine will not run correctly.

How it works is that the tank usually has a one way vale in the cap which allows air pressure from outside in which in turn forces the fuel up the pipe to the carby and then the carby pump comes into action.

As to information on how it works I will need to know what make the carby is either zama or walbro etc.

Here is a link to Walbro Carby info
