Hi Alun, and a big warm welcome to the forum.
It's good to have you aboard. We are a friendly bunch, and we all love to learn new things and tinker here!
To understand how it all works, you really should download a illustrated parts manual for the 2 stroke ATCO, from the Parts and Manuals area on the main forum. Instructions for accessing the manuals area is contained in the very first post in any topic on the main forum page.It will also come in handy if you need to buy spare parts, and will give you the specific part number for the flywheel pull start. You can then check the Outdoorking On-Line store to see if they have one in stock.
Alun, once again,
