Any tricks to holding the flywheel still while trying to tork the drive shaft nut down to 80lbs? Engine is a 88 force 50.

Get a cheap flywheel tool at a local auto store. Don't wedge a piece of wood between the prop you could break something.

remove spark plug and insert some clothes line rope into cylinder and that will stop flywheel from turning,when done back the flywheel up and remove rope.

Never heard of that one....

I took a prybar, wedged it between the starter, flywheel and starter bracket. PULL, Click click, Click click.

I've had my Flywheel nut come loose on my motor.. New lock nut as well.. Buy some thread locker and use it. Hasn't come loose yet.

This would have me very nervous about breaking a tooth. How can you wedge a socket on the block if the teeth are on the side, not the bottom?

I don't have to worry about the rose damaging anything while under stress? Is there anything for the rope to get caught on and not come out?

This also has me nervous about breaking something, did you torque your nut or just get it tight?

I use a ?? thick flat aluminum bars with holes to fit over 2 of the pull start nuts. Break-over off and torque on. W/O the bar touching the socket. JOW

I don't have those bolts, or a piece of aluminum like that, but that looks pretty good.

I have used that rope trick many times on many different motors and never had a problem:D

I ended up kind of using this method. I have 4 holes on the outside of my flywheel that fit a 1/4" bolt perfect, but they are not threaded. I took a 2X4 and drilled holes to match the holes on my flywheel and tapped the bolts through the board into the flywheel and wedged it against my tie down cleat.

Thanks
for all the neat tricks though guys.
