Last year, got brand new push mower from Wal-Mart. 5 hp Briggs and
Stratton. Worked fine the first few mows. Always used fresh gas. Then, it
started doing exactly what you described. Run low on gas, stop and refill,
won't start. However, was careful not to prime again to see if it would
start like that. Then tried the prime button a couple of times, no luck.
Long story, short. Found some crap in the tank and at the carb area. Spark
plug said it was running rich, deposits. Air filter was very dirty from
kicked up dirt as all was not grown over by grass yet. Cleaned all this up,
changed the plug, and worked fine. My conclusion was that the dirt etc. in
the fuel system was not a factor until low on gas with the engine stopped,
then it showed its ugly face.
Drained all residual gas from mower, after I ran it to the point of no gas
late last winter, and stored. Changed oil and added gas. Fired up fine
this spring. Dirt in air filter is not as much of problem this year, as
bare areas are covered with greenery now.
All current mowers are picky about the primer button, too much priming is
guaranteed to flood the engine. Without aids, at that point, you have
remove the plug and let it air out for at least a half an hour.
Same memory here when young. Drove the heck out of Briggs and Stratton 3.5
hp push mower. Mowed alot of dusty areas too including a self-made ball
field. The difference seems to be in the choke system and sensitivity to
airborne dirt. A 20 lb sledge hammer is more appropriate for these newer
"engineered freak" mower engines. But alas, we all don't have the same
laboratory conditions that these "engineering marvels" were meant to operate
in.
