These mowers use gravity feed to the carb. You may have a kink in the line or a plugged gas line coming from the tank. Try disconnecting the gas line to the carb and see if you have gas running out of the gas line.
I have a Murray riding mower and it has spark, gas in the lines, but only runs if you dump gas down the carb! Help?

I'd spray some Carb-Cleaner into the carb while it is running until it stalls, let it set an hour and start it up again. Try some carb cleaner additive to gasoline also, as it dissolves the gummy deposits in bad gasoline. Some gasoline is full of "garbage", like the cheap "no-name" gasoline especially.
Here is a very important note: Every winter you must put something called "STA-BIL Fuel Stabilizer" into the gasoline. You leave it setting in any 4-cycle gasoline powered device.
This stuff is not very expensive and will keep the gasoline from gumming up the carburetor when it freezes during winter months. I swear by it! Had many carburetor problems in the spring before I discovered STA-BIL (sold in any "Hardware" type of store in a nice dispenser bottle). (12/26/2007)
My riding lawn mower needs gas poured directly into the carburetor for it to start. Once it fires up, it runs fine, but even after I let it run for a few minutes I have to take off the air filter and do it all over again. Suggestions?
