Well I went and found a decent patch of long grass today in the back of my suburb.
I mowed for about 25 minutes and started on some mid-level grass 5-6 inch and then moved to some fairly thick grass knee high and the machine just kept ploughing through the grass. I was actually surprised how well it performed.
The machine was under considerable load for a fair period. I managed to fill up about 8-9 catchers of grass and neatly stack it around a couple of a large trees to keep in neat.
The mower never stalled, always started first pull after emptying the catcher. I gave it a good clean after the hard work and checked the oil to be safe and it was all good.
I appreciate your assistance in thoroughly checking over this engine to ensure its ready for a new home. I do enjoy being thorough with repairs and moving a machine from the scrap heap to a new home.
Unless you disagree Grumpy I am going to put the slight cough sound down too side valve engine misfiring like you suggested earlier.
