I used the mower the other day. Initially it started easily with just one pull after I stopped the engine. Then something happened one particular time after I stopped the engine. I pulled the rope to start it and I heard a crisp pop and I thought I saw fueled air bursting out of the decompressor. The engine didn't start so I pulled the rope again many times to no avail. I then removed the spark plug, gave it a few more pull, put the spark plug back and then only it started.
I do not know how a decompressor works. Could someone enlighten me?
More importantly, could someone explain what could have happened regarding the engine pop I heard and why I could not start the engine after that?
Thanks for your help!
