Bad Boy 27 hp zero turn mower

I have to blow into the gas tank with compressed air through the line to the fuel pump to get it to start. Starts up will cut for a while then start sputtering. I blow more air in the tank again and it keeps it running for a while. I have already replaced the fuel pump and fuel filter clean the the air filter. http://www.lawnmowerforum.com/images/smilies/frown.gif

I'll bet you have a clog either one of the fuel lines or in the tank. I would take of each line an blow them out. Drain the tank and blow and clean it out. I don't know if Bad Boy uses an in tank filter, you'll have to talk to you dealer about that.
