I like the design of the saw over all.  It is put together in a modular design.   I also noticed that the transfers are closed off with what looks like removable pieces.   So I guess you can say it is a closed port transfer.   Unfortunately the tops of the transfers were damaged so I will not be able to use the cylinder.   I am going to look for another used piston and cylinder to repair it if I can.   I will take some more pics as I put it back together and I will make some modifications while I have it apart.   Then I can compare it to the stock one I received from Kevin.

I was looking at your other 5020 a couple years ago and every part in it had a Husqvarna label molded into it.

I believe you are correct.   Even the cylinder had stamped Husqvarna on it.

The cylinder is 32.95.   I will probably get those from order tree not a bad price.

I wish that the piston and cylinder for the PP295/4620 saws and the PP310/315 were that cheap.

With all the machining done to the piston you would think it would have been more.   Go figure.

Yep.  Hard to fathom how they can sell a piston for just over $6 retail..............especially a piston for a stratto that has the extra stuff on the skirt...

It's pretty much the standard Poulan cylinder design now - even the PP338PT pole saw I recently modified was the same concept.  It's distinct from the Husqvarna cylinders, except for the 240 which is a sort of cross over design.  I think it is a clever way to make a simple casting into a closed transfer.  The castings seem to be well made. 

I like that it has the rubber coated bearings, which means that decreasing the squish clearance should not be too hard.
