Can't seem to find a diagram of the oiling system. Not sure if the line is clogged or if the oil pump is not working. I also have sprocket that is pretty chewed up.Any hints on how to replace the sprocket?

check your bar there should be oil ports on the both sides where it connects with the crank case. use a fine wire or a tooth pick to unclog. also may want to take a putty knife and scrape the saw dust out of the gap in the bar where the chain teeth run. if you have an external cluthc to change the sprocket you have to take it off.
