Thanks Grumpy, that is a great service manual. My engine is an '08 build but I imagine things would not change much.
One change I did notice was the a subtle difference in the air cleaner compartment design. The one I have has a fault which could cause dust ingress but bypassing the filter if you were to knock the front of the mower. The filter housing is not fixed solidly to the intake manifold. I'll try and get some pictures. The manual was great in explaining how to adjust high speed idle.
I had a quick read on valve adjustment but must have missed temp for adjustment, hot or cold?
