I replaced the front roller spring, I didn't realise that when I started mowing the height adjustment was slowly coming loose so the lawn got a nasty crew cut. But its come good now I just fitted a longer spring.
I fitted a new belt now it likes to drive itself when handle lever isn't engaged. Enough to be annoying going down slopes.
I can't really put much time into it now got heaps of uniwork, its mowing well so that's what really matters.. smile cheers2
