Well I took the mower out last night and gave it a good run for about 30 minutes in the long grass. I personally would rate it as one of the best performing mowers I have used in quite some time. The mower was taking care of thick above knee high grass with relative ease.
The engine was a little smokey however I am sure this was related to the lower than standard petrol to oil ratio. I then adjusted the ratio to what I like to call a rich 50:1 mix that was pretty close to a 40:1 mix simply because I was trying to be cautious in accordance with your recommendation.
The mower performed really well and emitted what I think was just a standard level of 2 stroke emissions.
I did have one minor query about the engine stop setup. When you move the throttle to the stop position is takes quite a few seconds for the engine to cut-out? Is there an easy fix to make the engine stop quicker or perhaps an adjustment to be made?
Otherwise I was very happy.
