My 5-6 year old lawn mower with Briggs & Stratton 4.5 HP engine is
acting up. Worked fine until yesterday when I refilled it with gas and
now it starts but engine stops in 2-3 seconds. Checked/cleaned the
plug and checked oil. Could it be that gas line is clogged and engine
is not getting continuous supply of gas? Any thoughts? thanks.

Bad gas.

It would appear you had bad gas or you stired something up from the tank
or the gas can.

Some guesses, and that's all they are --

1. Starts with a prime (assuming it has a primer bulb) but then dies
because the main jet is plugged.

2. If it has a choke, the choke is not releasing -- engine floods and dies.
In this case you should see heavy smoke as it quits.

3. The gas line from tank to carburetor is plugged -- in line with your
analysis. Same thing -- could be trash in the bottom of the gas tank.

When was the last time you cleaned the air filter? That and the other two
posts are all I can think of.

May be that there is water in the tank (perhaps from dew condensation).

I will check the air filter. But what do you mean "bad gas"? Do you
mean some dirt got into it?

"bad gas" usually means water or containments that does not allow it combust
normally. Water is the most common problem.

Take out the gas tank, empty it out and blow out the lines. Hemostats
are helpful with this procedure. Fill with fresh premium gas.

I simply removed the air filter and put it back and the mower works
like a charm! I can't explain it but I am happy as long as it works.
thanks for all the suggestions.
