Small Engines (Lawn Mowers, etc.): dynamark chainsaw parts, mild resistance, sprocket tip

Question

dynamark saw bar I have a dynamark 4242 chainsawwhich needs parts.  it has abar 17.5" long, "sprocket tip"  and needs a new bar, chain, and I think a new clutch/sprocket assembly.  The engine seems to start and run fine, but the bar is so worn the chain wobbles even when tight, and barely cuts despite spinning fast.  (the chain could even be the wrong one!)  With only mild resistance on the chain, the clutch disengages, and spins in the drum.  It seems to still be revving fine.  Where can I find which chain and bar would fit, and can I find a new sprocket and clutch?  Thanks!

Answer
I do not know of any Dynamark saw dealers.  Get a generic chain saw parts catalog.  You will be able to but the bar and chain, no problem.  The clutch may be more difficult.  In the catalog ther should be a cross-reference chart.  This guy claims to have parts.
