Im not being tricky, but I use an air gun... as locking up the motor is a pain, I did use a rag once fed into the belt at the crank whilst locking up the transmission in 5th gear with the footbrake on, that was good after a bit of stress. Also... dont laugh, as an apprentice I have locked up a motor with a light guage rope with knots in in popped in the plug hole and gently bring the motor up to TDC on the comp stroke, rope between piston crown and head locks the motor... but be gentle !
