Located on the right hand side of the carb, first picture shows the carb’s with one cover removed, second picture is of the needle slider removed from carb the is also a spring under each cover (not shown) the needle slides up and down in the main jet, the needle is tapered so as it rises it allows more fuel to enter. Check to make it slides freely without sticking also check the diaphragm (black rubber part on top of the slider picture one) for damage split’s etc. This can all be done with the carb’s in situ.
