Finished installing my new air compressor. Said screw it, not paying $80/litre for Ingersoll Rand air compressor oil, and just used the Rolair $60/4l jug of synthetic oil instead. Also replaced the guts of the pressure switch because the original one broke while getting the compressor off it's pallet [the compressor is REALLY top heavy]. And evidently the 'contact email' for a bunch of Ingersoll Rand service companies here in Edmonton go to /dev/null, got no response from any of them. Fortunately, kmstools had a Hobart-branded pressure switch that had exactly the same guts as the original switch for $60, less than what I could find online for non-oem replacement switch for IR's part number.
Also added a hour meter to my 52" walkbehind Snapper mower. Used a zip-tie to hold the wire wrapped around the spark plug wire, which was much faster and should hold better vs my previous method on other mowers of using rtv to glue the wire to the spark plug wire [really messy to do, and didn't hold very well].
Edit: Also replaced the thumb-screw drain valve with a drain valve connected to a cable from kmstools ($15). It sucks getting under the tank whenever I use it to drain the water. This way, just walking by I can pull on the cable and it drains the water. I considered an automated drain valve, but at $200+, I think I would rather remember to pull the cable every once in awhile.
