These saws both use a crankcase pulse operated diaphragm type oil pump, I believe some models of the Super2 did go to a pressurized oil tank system and it appears that both types have had problems. I received a Super2 in pieces and it was a nearly complete saw except for a few missing items, one of which was the entire diaphragm oiler system. Not wanting to spend a lot of money on this saw, I decided to make my own pressurized tank oiler. Attempt #1 was to install a nipple in the crankcase hole that would have provided pulses for the missing oiler, then I ran a line from the nipple to the oil tank with a check valve on the end, and ran another pickup line with a filter from the tank to the nipple on the rear of the bar mount. Result was WAY too much oil.
Attempt #2 was to drill and tap a hole in the bar mount boss that let me install a machine screw that would block the exit oil hole in the bar mount base, thinking it would give me an adjustable oiler. Very limited success, the adjustment was too sensitive, too much oil or not enough. Might have worked better if I had used a screw with a finer thread than the 6-32 I used.
Attempt #3 was to drill a small hole in the oil tank cap to reduce the pressure in the tank. Started with a #55 (0.053" dia) drill and the hole was too big. Result, no oil. I experimented with placing various size wires in the hole to reduce the hole size and eventually found a small nail (0.048" dia) gave just the right amount of oil when cutting. My sketchy math shows a 0.025" drill probably would have worked if I had one. A surprising result is, at idle there isn't enough pressure in the tank to deliver oil and when you shut the saw off, the pressure bleeds off right away and it stops oiling, unlike most pressurized tank systems.
