Hello Daniel,



Thank you for the reply, if the spark is OK and the carburetor has been cleaned out I do think that it is likely to be kickback from incorrect spark timing. I would still remove the spark plug and give the rope a pull to verify that there is not any fuel in the cylinder, prior to removing the flywheel. If not, then inspecting the flywheel key will be in order.

Watch this video

to see how to perform the flywheel key service for a similar engine.



Please let me know if you would like any further assistance.

Helllo Jerry,

I figured timing.but I did not know what determined it. I guess I have to pull the flywheel. The sequence I followed was no fire, pull plug clean and test (good), reinstall. Add fuel to carb., it turned over. Pull carb. quick clean, reinstall, gas flooded out like needle would not seat. Pull carb. clean good(a lot of gum) reinstall. This is when it nearly riped my arm off.
I will wait for your reply, plus I got to find a puller I'll bet.

Thank you for your time/help,

Daniel

Hello Daniel,



 



I'm sorry to hear that your mower is malfunctioning and I would like to assist you.  The issue that you are describing is usually caused by the timing being off and the spark firing at the wrong time in the cycle.  This is generally caused by the key that secures the flywheel being sheared, sometimes completely.  A fuel issue will generally not cause something like this, unless the cylinder is full of fuel and you are actually feeling the kickback from that condition.  I would like more information, such as if the spark plug has been removed and if it tries to fire at all. 



 



Please reply and I will be happy to assist you further.
