Not sure what you are referring to on the 028, BUT are you sure you need to modify the oiler? the 028 spews oil much more than any later saw... Never seen one that doesn't oil liberally if the pump and delivery is working correctly.
oiler
If the oiler is not using a tank to a tank on an 028, you may have worn parts. This saw is not an EPA model.
First place to look is the screen in the tank. Clean it. The you will need to pull the sprocket and clutch. Best bet, a worn pump housing. The pin hole in the housing gets worn, which lets the pin move, which causes the pump piston to lose full stroke.
