Think that you would run the risk of twisting the crankshaft.

Don’t tell me there is another tool to lock the crank on that side.... ??? I think I’ll go with the airgun and use the expert trick, “bloody tight”

The reverse thread nut on the right hand end of the crank only holds the starter clutch onto it's taper and does not require a lot of torque like the jesus nut on the left hand side that holds the drive sprocket in place. I just give my 10" socket bar a few whacks with my nylon hammer to tighten or loosen it, it is a shallow nut not meant for high torque load.

Ok great! So I will do! I read somewhere it needed also 10kg as the jesus nut... probably my mistake.
Thanks!
