I have one of the variations of these that was passed down from my father and I'd like to get a new piston ring, a carb kit and sprocket. It's got 90-100lbs of compression. I took it apart today and the piston/cylinder don't look too bad, better than my 346xp was and a new ring did wonders for it.
Where can I get parts for this oldie? A shop manual would be nice too. I have no clue how I am going to keep the new ring compressed long enough to get it down past the crank area and into the cylinder. Oh, and the foam air filter is rotted also. Can I just cut a new one from any foam filter with good effect?
Also, since I had to split the cases to get this thing apart, will I need new crank seals?
