that vid shows a setup very similar to what i replicated with my daughters. The main engine hangar bolt has a nut on top and underneath the plate on the swingarm. you have to loosen the top nut, then go underneath and run the nut on the underside clockwise to move it closer to the engine. Then you can use the adjuster on the right to pull the engine upwards to tighten the chain. If you don't run that underside nut down the shaft, it will not get any tighter.
in the pic below, you can't see the underside nut on the left, its hidden by the tubing.
