Otto, my pump is stock mechanical and new. I don’t have a pressure gauge but the bowl holds pressure and fuel squirts vigorously when the fuel line or carb filter head is loosened. I can visualize a sticking needle to be the cause and will check it next. When I pull the carb I’ll be able to see in the manifold.
Jerry, how would you check the float level? A height gauge would be ideal but there’s no way to manipulate a caliper to contact the machined surface and the float.
Thanks to all for your inputs. We have company coming today but I’ll be back on it tomorrow!
