put the fly wheel on then put a screw driver through one of the bolt holes at about 2 o'clock and it will stop the crank from spinning.........make sure its a good screw driver not piece of crap or it will break

 

i usually take the oil pan out and stick a piece of wood in the crank. ive never damaged anything and done it alotttt of times

 

^ that's a good way to get dirt inside the engine.

 

Yeah, some of the reviewers on Amazon say they wrap the tool with some duct tape to thicken it up a bit.

I'd say if you have the ~$50, get the Honda tool, then you only need one breaker bar with a socket. I think someone I know has one of those tools, it's badass.
