Thank you for the reply. Wish I could post the photo - I am new here - yes I suppose it serves the same function. You guys have literally saved me a lot of pain - I thought that screw was crucial to correctly position the wheel.
I removed the screw and manually aligned the main axel nut and tightened it - the chain is also in the correct tension too - thank you
