The saw starts first pull and runs fine but it has no power I have adjusted the carb. It is also blowing a brown oil from the exaust smokes a lot.

You're using a two stroke oil/gas mix ( 40:1 or 50:1 - depending on the oil mix directions) aren't you?

It's likely in the carburetor. The best thing to do is to not worry about pinpointing just what in the carb is leaking, but put in kit in it. That's where you usually wind up anyway. They aren't expensive and most with moderate mechanical skills can stick one in them, just with a little care.

Sounds like it's running rich. How did you adjust the carb? Can you lean the high speed and make it run better?

Does it have a spark arrester on it? Perhaps there is an exhaust screen that is all carboned up.

Will try to adjust the high setting again seems like it is have little affect turning it slightly made no difference so I tried several turns and it was still almost the same.

When you can't get anything out of the adjustment screws it's usually in the reservoir diaphragm or needle valve. One or both are leaking.

It could be leaking. started working on it today and found fuel in the air intake. It is also hard to pull the starter rope. I have tightened high and low and opened both 2 turns. need to wait until rope is pullable before i try it again.

Take the plug out of it and spin it over a few times to blow the gas out of it. Tie back the plug wire so it doesn't spark and start a fire.
