Starting Problem

Thanks guys, yes i do pump the throttle before starting. It turns over excessive before starting or sometimes it will run the battery all the way down if i let it. Thats with me pumping it and only turning it over for a few seconds at a time. This morning it sat for a day, i pumped it once, turned over fired right up, i feathered the trhottlr and it kept running fine! So i don't know, its possessed. Then when i got to work and shut it off, tried to restart and the battery was dead, its always something with this P.O.S.!!!!
