I"m still trying to figure out my Yammy fuel starvation problem. Replaced the primer bulbs, they work fine, re-routed and tried different fuel line hookups but, I still can't get the bulb to prime up nice and tight. I found through my trial and error procedures that there is a one way check valve in the brass fitting right where the fuel line connects to the gas tank. The ball is nice and loose, it holds pressure when you put a vacuum on it, is it possible that the spring in this assembly has gotten weak and is not doing its job?? You can pump on the primer bulb all day and it won't firm up, all fittings have been double checked, no gas leaks so pretty much down to this one way valve thingy.........Sherm
