Poulan Pro 300 EX, B&S 18.5HP, 42" Cut, Model PB18542LT, Product 960420088 with a Briggs & Stratton 18.5 500cc I/C Model 31N707, Type 0301 B1, Code 0903162D, Engine.
Recently purchased several years old, riding mower already had a large generic fuel filter (I have changed oil, blades, deck belt, air/pre filter, spark plug and greased it). I added a B&S fuel shut off valve (searching for new fuel filter). . The shut off valve is between the carb and the fuel filter. The fuel filter is between the shut off valve and the fuel tank. Yesterday, after mowing, I put it in the fastest gear it has (6th gear) with the blades disengaged as I was driving back to the garage on level ground. The engine began to sputter as if it was running out of gas or had water in the fuel. I stopped and found that I still had about 1 inch level of gas in the tank. I slowed down and it stopped sputtering.
Does my engine have a fuel pump or is it gravity fed? If it is gravity fed, is the open shut off valve reducing flow when there is less gas in the tank? Should I remove the fuel shut off valve? Or should I look eles where for the issue?.
