I am so lost on this i got it from a friend because he couldent get it to work i found that there was this plastic needle with a o-ring on the outside of the carb that was leaking when i tried to prime it i replaced it and i can get it to start but it will run for a couple of mins then act like i has ran out of gas. I have cleaned the carb all the gaskets look good cleaned the muffler. Now here is the fumnt part when i go to start it after 2 pushes on the primer bulb gas will pour out of the muffler and spit everywhere and i have to take the spark plug out and dry it off or it wont start and the way it acts ive been thinking there is a problem with the tank if i take the fuel cap off with it running and rev the motor it will put pressure in the tank and splash fuel out but i just dont know what to do ive taken the fuel filter off no change the breather cap on the 3rd line no change several people have worked on it before me but im out of ideas
