I am assembling the 7M on an engine stand. There is no way I will be able to tighten it like the manual says too. I am thinking a length of flat bar stock and drill it out and bolt it to the back of the crank with the flywheel bolts and then when the metal bar stops the crank from turning tighten it that way. Or is there a better way? Also my tourqe wrench only goes to 150 ft lbs do you think that will be enough?
