Hi Grumpy, check the mower parts against the supplied picture, and its all good. Hoping I was right about the washer I found, and I was. Put it all back together, double checking as I went. Got motor completely back together, double checked governor arm as you suggested. Double checked everything again. Fresh oil, new spark plug and air filter, couple of soft pulls just to get a bit of oil every were. On the second actual pull kicked over, now running smoothly from idle up to full revs, even in the thick grass. Thanks heaps Grumpy for all your help (and patience).
