Cessna 1 #1 Posted September 11, 2011 Yesterday I replaced the fuel pump on my GT1142. The old one was a Walbro autopulse 3020 with a B & S 80865 since the Walbro inlet came apart. The tractor will start and run a couple of minutes then quit. If I put some gas down the carb it will start and run. Any suggestions as to what would cause this.

Irv 115 #2 Posted September 12, 2011 1st thing I'd check is the vent in the gas cap. Next, the fuel lines and filter and the gas tank outlet for dirt/plugging. Share this post Link to post Share on other sites
