Default how to clean a lawnmower's engine (stalling problems)

fantabular wrote:

I've been having problems with my Murray lawnmower. It idles very low
and stalls frequently.

This problem started when the wheel broke on my lawnmower, so I had to
tilt the mower back to add a new bolt on it. Since i did that, all
kinds of fluids are inside parts that aren't supposed to have fluids.

I took off the part above the gas tank (sorry, I'm a computer geek,
not a lawnmower handy man, so I don't know the names of these parts)
and noticed that the greenish colored filter was soaked with a liquid
that smelled like gas and looked like oil. I squeezed it dry as much
as I could with a large rag and replaced it.
Then I removed the spark plug and noticed that there was oil in the
threads and the top of the plug was very black and looked burnt. I
wiped it clean as much as I could and replaced it.

Then I added new gas since I heard that last season's gas might be the
cause of the low idle problem.
I still have the problem of low idle and frequent stalls.

So basically my question is this: what else can I try and how do I
clean all the parts that're full of fluids that aren't supposed to be?

Thanks in advance!

Just raise your idle speed with the adjustment screw. Your air filter is
supposed to be oiled. Reoil it. Stop fixating on the fluids and replace
your spark plug if you are looking for something to do.
