You can find TDC on just about any engine by inserting something in through the spark plug hole, say a small screw driver inserted up to its handle, you want it to protrude far enough in to contact the piston somewhere just before TDC. Rotate the engine until the piston just contacts the end of the screw driver, mark that position on the flywheel. Rotate the engine the other way and mark the flywheel again when the piston hits the screw driver. Halfway between those marks is TDC.
