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 ?
