So I have an 04 350 and basically it sat for about a year and a half. It seemed to be running ok the last time I had it out. I changed oil, valve cover gaskets the exhaust looked like it was leaking, drain the carb of the old gas and the tank as well. So I put new gas in and brand new battery and she started with a couple of cranks. She will run with the choke on but after turning choke off or putting it into to gear it will not keep running. Any ideas on were I should start looking?
