tension it then turn the egine over by hand through 360 degrees, the longest section of belt should twist through 90 degrees any less its too tight
any more too slack. the odd degree doesnt really matter.

Cheers thanks for that, longest run on belt from exhaust cam pulley to crank does twist 90 degs with a little effort.
I'll put the rest of the bits back on in the week then wait for a brave moment and turn the key

...and it's 2 full turns to get the timing marks to line up again and a 4stroke.
