Here's the deal: About a week ago we noticed oil and gas spitting out of the carb into the air filter. Changed the air filter and kept an eye on it. Definitely not spitting out as much but still a little bit. Now the blower will start but dies within 5-10 seconds (I can play with the choke to get it to run for maybe 15-20. I have: - removed spark arrestor (muffler screen) - changed spark plug - changed fuel filter - changed air filter - disassembled and cleaned carburetor I don't know if the gas and oil leaking out has anything to do with it or not. Please let me know if you have any ideas.
