Remove the bar and chain. Run the saw for a few moments--it should ooze out oil from a side port where the bar fits to. If ok, clean the drive end of the bar oil passages, particularly the two small channels that run from the large holes out to the chain groove on each side. Clean the entire chain groove. If no oil came out of the port, the oil pump, connecting lines, and tank filter require attention. When everything is back together, run the saw for a few moments with the tip near some cardboard--it should throw off a thin line of oil onto the cardboard. Hope this helps.

If there is no oil getting to the chain, you will have metal to metal contact between the chain and the bar with no oil film, the chain will look dry and be covered in baked on resin from the heat, make sure you have adiquate chain oil in the oil chamber, this chamber is seperate to the fuel chamber, it should be filled with a non fling chain oil.
Chain stretch is usually caused by inadiquate oil/ or incorrect oil to the chain, aim the tip of the bar at a clean peice of timber, you should see a good line of oil spray from the tip of the bar onto the timber. Very dirty or dusty timber will also dry the oil out on the chain, and cause chain stretch.
Some saw manufactures design their oilers to only work with their bars. Are you running the mfg suggested or stock bar? Chain? Stihl Chain is designed to use 30% less oil because of oil groves cut into each drive link directed to the rivets. So if your running an aftermarket bar/chain, the oiling ports may not line up. Especially if it oils with no bar & chain
Remove the bar and chain and clean the side of the engine where the bar fits. There is an oil port there that should ooze oil out when the engine is running fairly fast. If it does, then clean the drive end of the bar (large oil holes out to the chain groove on each side. Also clean the entire groove and oil the sprocket on the outer end (if equipped). If oil did not ooze out of the port, the oil pump, oil filter, and any intervening lines should be inspected. Once you have oil proceeding from the port, reassemble the bar and chain. Check for proper oiling by running the outer tip of the bar (at speed) near to a piece of cardboard--it should throw off a thin line of oil onto the cardboard. Hope this helps!
Well, you have 2 choices. First one is to buy a new chain. Second one is to take your chain in somewhere and have a link removed. If you think this chain is that stretched you should check your chain oiler and make sure that it's working. Take the chain and bar off and run the saw and look at the oil port and see if oil is coming out. Also check the oil ports in the bar and make sure they are clear. The only way a chain can get this loose is from wear in the pins in the chain from running dry or too tight. Also make sure the surfaces on the bar where the chain rides are flat and square or your saw wont cut straight. Hope this helps you.
