Brand new. used chain oil and had to refill the resevoir so I know the chain was being lubricated. Saw starts to cut, then just burns the wood- the teeth on the chain don't bite.
The blade is no longer sharp, something not unusual after about an hour of cutting. How long a blade stays sharp depends on what type of wood you're cutting, whether the blade contacted the ground or anything other than wood at any time, and how hard you are working the bar through the wood. If you are cutting hardwood or something like railroad ties the lifespan of the blade is greatly reduced. You can easily sharpen the blade with a hand file or dremel tool with a chain saw blade kit on it or have the blade sharpened. Best practice is to have one or two extra blades so you can change them as they become dull.

The make, model, and occationally the serial number help us solve your problem.
Does the engine quit running? (Carburator needs adjustment)
Or does it continue running and chain stops? (need clutch refaced or replaced.) (to aggressive a chain for the size of the engine)
I think you replaced parts unnecessarily. Maybe quicker and cheaper to visit your friendly neighborhood chainsaw shop. A good one can repair it even if they do not sell your brand.

Hello Sam;
Sounds like your oiler is not operating, try this please:
Oil System Plugged:
If it does not oil on completion of 1 it is most likely a bad oiler or worm gear (see IPL). Post back (below) with a model and serial number if no ooze and I will provide an IPL.
If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH

The washer and nut holding the tension on the bar may be oily or stripped. You can subsitute with a locking washer and thread tape.

Modern chainsaws have the ability to run without turning the chain via the chain-brake. To set the brake the uppermost handle is pushed forward (toward the chain) and a firm snap should be heard and felt. To release the brake you pull the same handle back (towards the engine) and get the same "snap".
Concerning oil leakage: Bar/chain lube collects on the inside of the clutch cover and the sawdust mixes with it as you saw. A surprising amount of oil gets absorbed in the sawdust and later seeps back out when the saw is at rest. If the level of oil in the tank noticably drops after sitting overnight you may have a leak...otherwise it's normal.
As for a running chain that wont cut, it is common for chains to be installed backward and the unit still function perfectly (it just won't cut wood). See the proper chain orientation here. In this photo the chain travel is from left to right.

Remove the bar and chain from the engine. Clean the side of the engine where the bar fits, start the engine and run fast for several moments. Oil should ooze out of a port and run down the engine side. If nothing, then the oil lines, valves, tank filter, and the oil pump (behind the clutch assembly) should be checked for plugging, breakage, or other problems. If oil comes out, then clean the oil holes in the bar drive end including the two small holes that lead from the larger holes out to the chain groove on each side. Clean the entire chain groove. Oil and check the end sprocket for smooth, relatively free turning. Compressed air is very useful for cleaning these parts. Reassemble bar and chain making sure the adjustment tang drops into one of the large holes--you may have to back off the adjustment several turns to make this work. Make sure the chain cuts toward you on the bottom run and install the clamp nuts/bolts finger tight. Adjust the chain until it pulls up to the bar and you can turn the chain by hand. Run a line of oil around the chain to pre-lube it. Tighten the clamp nuts and retest the tension again. If ok, start the engine and run for several minutes, then place the tip near some cardboard and run at speed for several moments--it should throw off a thin line of oil. Make sure the chain is fully sharpened then try a few cuts. It should cut smoothly without any undue pressure from you. Hope this helps!
