Great job Smelmechiz. I do enjoy seeing others keeping the "oldies" alive and more importantly, using them!
Check your nuts and bolts over the next few mows. You never know which ones might shake themselves loose if you have inadvertently not quite tightened them up properly. Put a few drops of oil into your oil holes either before or after every mow and check that your clutch is adjusted properly so you don't wear out the thrust pad needlessly. It should give you years of service if you give it 30 seconds of care each time.
Enjoy the mow.
