Awl--
Got a Husky HD special, 26 gal upright, cast iron head, oil, belt, single stage, sposedly good for a zillion hours, etc. Perty happy with it, mostly cuz it's quiet. SpeedAire and others seem to use this same cast iron head. Lately, the speed varies; starts fast, slows down, eventually speeds up, slows down. Set the motor for 220, juice is OK, etc.
What do you think is happening?? Compressor proly has 10-20 hours on it. I know compressors can be slow when cold, but I don't think this is a factor, as it will slow down/speed up during operation, in an already warm room.
Also, how do you generally measure oil level w/ the stick: Pressed all the way in, or sitting on the lip? The stick is a plastic press-fit jobby, not threaded, w/ a vent hole built in. Is this vent important?
Last, is overfilling w/ oil disastrous? Say, by about 1/2"?
TIA!
