I have a Lawnboy model 6872 or maybe 7268.

Anyway, it was running fine, then I noticed that the power went down
and it started smoking.

After it cooled, I started it and it ran more or less normally then after
4 or 5 minutes starts smoking with low power.

Compression seems normal.

Anyone know what happened or how I could figure out what happened?

Is it possible for you to check the compression when it is hot ? Something
must change as it heats up.
Do you have to keep adding oil ?

Sarge

if its a 2 stroke , exhuast may be clogged up.

Or just the airfins could be clogged with leaves and grass.

What color was the smoke? Black or white?

Why would it be white? Does it have a radiator?

Color of the smoke goes a long way for trouble shooting....

The whole story is that I got lazy and took it to a shop last winter to
have
something done. I got it back and started using it. A few weeks later
it started
the gradual process of smoking and losing power after it warmed up. It got
progressively worse.

I temporarily got unlazy and started to take the carburetor off when I
noticed
the bolts/screws holding it on were loose. I tightened them and
everything seems
to be fine.

The only confusing thing is that I would have expected the mixture to have
gotten lean not rich.

Thanks for coming back and explaining. Nothing worse than to be left
hanging.
