Hi Joel, sure that will free the needle, but I am well aware of a sticking needle well before I assemble the primer cap on the carb. As soon as I fit a needle and then make sure the float clears the post if the needle is going to stick it sticks straight away. A tap on the primer cap will dislodge the needle but I am not confident then that the needle will drop once it is in the carby. Some then work fine, others don't and as you know it is nearly impossible to prove that this is the problem. It is ok for me as I can swap parts around so I can get one to work but even so I can't guarantee that the float will continue to work. When I get a bit of time I want to sit down with a known working carby and go through the needles in my failed box to test every one of them . Some are going to be ok, but as soon as I have a non starting problem the first thing I do is swap out the needle because that is the most suspect item
