I have a pressure tester but I use it to test pressure/vac on crankcases. How exactly do I check that? Just connect it to fuel inlet? Vac or pressure? Of course vac I would have to hold it upside down.
My local small engine shop just said to adjust the float to where the fuel flow shuts off quicker. And if that doesn't work it would have to be replaced and he said good luck finding one. Which I have seen plenty on the Internet. this is why I tinker with them on my days off from the fire station. I used to work at a small engine shop and I love it but I still have a lot to learn.
