Why Small Lawn Mower Produces Smoke?

Smoke comes out from machine

When I cut grass on my yard with my small lawn mower, the problems always the same:

- smokes come out

- when I stop the engine, then machine oil was leaking into filter or prime bulb

In case of cloud (smokes), it is said (from internet searching) few possibilities:

- Oil in the chamber is too much.

- Oil leaking when tilting the lawn mower to the filter or prime bulb

- engine is too hot.

Previously, whatever possibilities, I always face with two choices: bring it to a repairman or just simply buy a new one.

Since cost to fix machine almost equal to new one, I usually buy new one for several times.

My front yard

Recently, I found the answer why my lawn mower produces cloud, it is related to over full oil and leaking oil. 

I used to run the smoked engine until it stops, then re-start, stop, re-start it up and stop totally. 

But now, after stopping the smoked engine, I let the engine cooling down for a while. Draining some oil out. Check the oil level by available dipstick.

Drying the lawn mower under the sun for 15 minutes. Push red prime button for several times, and start the engine. It works. 

I am happy with my yard lawn mower now. I fixed the problem. Hope, it would work well at least for this year.
