I got a 1986 Hustler 900 with the G50B Chaparral. The carburetor is Walbro WDA-30. I had the pump rebuild, and the carb adjusted. It runs just for a couple of minutes, and then stalls, cause the pump won't pull the fuel out of the tank. It idles just fine, as long as I want it to. But if I wanna drive it, it runs sometimes 10-15 minutes, sometimes it stalls after a minute.
I replaced the vacuum hose, which is driving the fuel pump, but it just wont work. If I put a jerry can near the carburetor, it runs fine, too.
Any help would be appreciated.
