So I’m told to put nylon rope in my cylinder on tech to torque flywheel bolt..
I am not gonna do that and break my piston at the wrist pin.. I don’t have a special tool for this.. any ideas??

Yep, put nylon rope in the spark plug hole and you will be fine. I do it all the time.

The other alternative is to hold the other end of the crank
Easy to do if the blade is there

That works as you being using the engine's PTO pulley or you can just use a large flat blade stuck in the flywheel ring teeth and held up against the ignition coil mounting stud. If I can torque 48M series flywheel to 140 ft/lbs using ignition coil stud then torquing the 31 series to 110 should be fine which I have also done here. Just make the ignition coil is mounted it stabilizes that stud.

I just did the 49M flywheel yesterday.

Thank you all who responded to my post..
Lawn mower is now running correctly, I ended up ordering and installing a new fly wheel key.. the motor ran wide open with no throttle control.. I set the Governor shaft and it idled down but still not much throttle control, which ended up being the throttle plate adjustment.. now everything is just fine..
And the loudness has also went away, it seems the flywheel key was the culprit of all that exhaust noise..
All is well that ends well..
