    Default 725R runs 2 seconds then dies

    I have to continually push the primer bulb to keep it running otherwise it will die within 2-3 seconds of being cranked up. I tore the carb apart and everything looked fine. Upon reassembly I noticed that fuel runs straight through the inlet into the left side of the carb where the diaphragm is and then bleeds out the small hole in the venturi of the carb. The diaphragm didn't have any tears, etc that i could see. Is there a rebuild kit for these carb's? Or do I have another problem? Thanks

    Edit: Upon looking at the pic's that have been posted I noticed I had my fuel lines routed incorrectly. Even after fixing that though it will still only run about 5 seconds after being primed then die. Any help thanks!

    I can understand where you are coming from! However, I used to make similar gaskets and found that there can be miniscule tears in the fabric of the gasket that can cause this same problem. The easiest solution is to purchase a carb kit for under $12 and rebuild it yourself. I have learned that if a person can operate the thing, they are more than qualified to fix it. Try it! Let me know what happens...
