I found a fuel filter in the fuel line between the fuel tank of my Snapper walk behind mower and the B&S carburetor.
What are the advantages and disadvantages of such a fuel filter? Is it worth while installing a simple filter if the mower doesn't have one?
How likely is it that a filter will become plugged up and fail to pass sufficient fuel? When I disconnected the fuel line at the carb when the filter was in place, fuel would drain out of the tank. But could that fuel flow still be impaired enough to prevent operation of the engine if the fuel filter was partially plugged?
My B&S engine would start if gas was added directly into the carb, and run fine for 15 seconds until that fuel was consumed ----then the engine would stop. I've presumed that to be a bad carb, but replacing the carb with a $14 B&S knockoff made no improvement.
There was a simple fuel filter in the fuel line. I thought that might be plugged and impairing fuel flow, so I removed it and installed new fuel line, since the existing fuel line was old and marginal. I removed the fuel tank and cleaned the crud out of it by repeatedly adding gasoline and agitating the fuel tank, then pouring out the fuel. After several repetitions of this the fuel now runs clear.
How likely is it that the fuel filter could have been plugged up enough to prevent fuel from getting to the carburetor? I could prime the carb to get the engine started briefly before it quit, suggesting that fuel was getting to the float bowl of the carb, but perhaps not enough to keep the engine running?
