Hi all, I have had some queries on the web site regarding the power the drill can provide on the pull stroke.
There is a design 'trick' inside the unit that means when the cord is being retracted into the engine, the drill is working to stretch a bungee cord.
That means that on the pull stroke, the energy stored in the bungee cord is added to the power of the drill, resulting in a very impressive, powerful, speedy pull.
A good quality drill is still required for larger engines - I am OK to comment here or will reply personally via any web-site query regarding the power that your drill can deliver (if you provide me with your drill make and model number)
