Thank you AVB for your information on compression. Is comforting to know that compression is about average, saving owner the cost of a rebuild.
Thank you bigted for your compliment on my first valve clearance adjustment. Checked the blade and one side had more meat on it than the other due to the way it had been sharpened. Didn't notice any significant variation on the driveshaft, but looking back over the photos of the single blade, it looks like it was slightly bent/twisted. I fixed that slight bend/twist by accidentally bending it more when I was running it around my yard and clipped a lump of concrete and now the blade needs replacing altogether. It may be me, or maybe someone can tell if the blade is bent in the two attached photos. In the first photo, the left hand side of the blade seems to have the same crisp angle as the right hand side, which also has more meat on it. The second photo is taken from the opposite side view, the blade was not moved, just me walking around to the other side, and the angle on the right (previously being the left in first photo) is still looking bent/twisted when compared.
On the shakey issue, the motor is rubber mounted and, without the blade attached, the engine still is a little shakey. Maybe a better way to describe it would be that "It has a slight sideways vibration".
Apart from the new blade now needed, it is back in working order. :-)
Thank you to all who have contributed in helping me get this mower working.
Much appreciated.
