3 1/2 hp B&S. Starts, then immediately stops.
Once I prime my lawn mower 3-5 times to start, it starts right away. But once the primed gas is used up, the mower dies. I have taken the gas tank off, removed all the old fuel and cleaned it out with paper towels. I also took the carb off the tank and blew compressed air through all the ports I could see, which seemed to be open. I also installed a new spark plug.
To recap, it only runs on the primed gas. Any help would be greatly appreciated, as I have been out of work for the last 6 1/2 months, and am trying to save $$$ by doing these things myself.
Thank you in advance.
