    Always?

    Or just when you've been pressing the tickler? If so, don't worry about it.

    When the fuel level is very high, because of tickling, petrol can be blown out of any of the holes in the carburettor by the piston rising on the compression stroke while the inlet valve is still open.

    The inlet valve does not close until about 60 degrees after bottom dead centre, depending on how sporty your camshaft is.
