No mate. It's lubrication comes from the oil you add to the fuel

Went to start my XL500 homelite chainsaw and the rope won't pull out.It worked fine when I ran it dry for storage, now it seems like th sprocket won't turn. looks like chain oil is comming out

If it is bar oil then the gasket is leaking between the oil tank and the crankcase, this would mean a full strip down and replace the gasket.

Oil is going into cyl.

If you are saying chain oil is entering the cylinder then you either have the gasket gone between the tank and the crankcase, or the crank seal is allowing oil from the oil pump into the crankcase.

I was putting a new chain on my 445 and the bolt that holds the bar on fell down inside the saw. How do I get it out?

You need to empty it out through the oil filler hole, drain the rest of the oil out, a tool with a magnet will aid puting it back through the the filler opening and back through the crankcase, as there is a square on the back take care to make sure it ligns up with the moulding on the inside of the crankcase.

Poulon pro 18" smoking

The only way a two stroke can smoke is either it is running far too rich ( possible blocked air filter ) or there is too much or incorrect oil in the fuel, if the oil tank for the chain is sepereted from the crankcase by a gasket, it maybe the gasket leaking and allowing chain oil into the crankcase.

I have a mcculloch 16in. chainsaw and it is leaking bar oil out of the bottom of the chainsaw as soon as i put it in. what could be the problem?

I would say the tank is cracked, take the bar and chain off, fill the oil tank with fuel, this will leak out much faster and you should be able to locate where it is comimg from, if it is the tank, many of these machines incorperate the tank in the crankcase.

Cannot start saw because of compressionon engine, cannot pull cord because of compression. saw is a jonsered model 670.

Not being able to pull the start cord because of "compression" is usually a sign that the cylinder head is full of fuel and/or oil. Take the spark plug out and try to pull again. look at what is in the cylinder, fuel mix or chain oil. If the engine turns over, pull several time to clear the cylinder. Clean the plug and put it back. Gas/oil in the cylinder means it is leaking into the crankcase. If it is chain oil in the cylinder, there most likely is a crack in the crankcase. If it fuel look for a leak the allows the fuel to get into the crankcase when it is stored.

I would like to know what type and grade of crankcase oil is used on a MS-1635 McCulloch 16' saw

There is no oil in the crankcase of a 2-cycle chainsaw engine, it is mixed into the fuel.
McCulloch recommends 40:1 (1 Gallon of premium fuel/3.2 ounces of quality 2-cycle oil).
It will operate better on 50:1 (1 Gallon of premium fuel/2.6 ounces of quality 2-cycle oil) once properly adjusted.
If you are asking about chain lubrication, purchase whatever "Bar and Chain Oil" is least expensive at your local hardware or home center.

I have a older remington gas powered chainsaw (model SL16)- I rebuilt the carb (new diaphragm and gaskets), started it , did some adjustments and it ran great- When adding bar oil to the bar oil tank and...

An impulse line from the crankcase pressurizes the oil tank to force oil to the chain. On the bottom of this line in the oil tank is duck (one way) valve. I think it has failed (open) and you are sucking bar oil into the crankcase. Loosen the oil cap before putting her to bed to help stop the bar oil from weeping. Key word Help. LOL HTH
If this doesn't solve your problem try here: Chainsaw thread (free to join)
Do a search for your saw it has probably been asked and answered. They will help if my suggestion doesn't work and you can't find an answer.

Older homelite super 2 has bar oil getting into cylinder

Sounds like you have a leak in your crankcase. On most ( or at least quite a few) saws the oil tank wall is shared with the crankcase housing. When you add bar oil it's running into the crankcase and then the cylinder. It may just need a new gasket, worst case is you have a hole in the housing.
