660, you sure on the wear limit of 1mm? that's .0393, that's huge?
That sounds huge to me also but that's what the service manual says.
We should share what we know... someone may learn...

The main goal for me here was to play around without being too far in if I mess something up. So far so good there. This saw will just be an occasional user, only because I don't have a lot of cutting to do and a bunch of saws. I do want a good runner. Checked squish parallel to wrist pin and ring in place. So far most the grinding I did was on the exhaust side. The intake looks better to begin with, where as the exhaust side is angled down and seemed more choked up anyway. Not going to do a lot, least not for now. Want to do a little in the upper transfers since the windows/covers make them so easy to get to. Then I'll see how it runs. Probably open the muffler up some too. It is a nice empty can to begin with. I'm not expecting a cookie cutter or anything, just a decent little saw. If I get decent power out of it could be a nice little camp saw.

I got the ports all done, at least as far as I'd like go for now. I think I did fairly well considering this was my first rodeo. I'll get some pictures up later to be critiqued.  ;D One more question, what's best for cleaning out the cylinder of all the metal from grinding and sanding? Soap and water? Baby bottle brush? Dishwasher?  Thanks.

I wash them in gas, then use a air gun.

Well, been a little busy and haven't had much time to play around lately, but wanted to throw up a few pics I had.  They're not the best but you can see where I opened up the exhaust and rear transfers some.









I have since done a little more on the exhaust, evened it up a bit and smoothed out the inside a bit more.  Looks pretty good, just waiting on a few things to come in and then I'm going to put it all back together.  Can I use liquid gasket material for the transfer port covers too?  I forgot to order then at the local guy and he gets stuff slow as hell.  Maybe just temporary?  Thanks.

I may be showing my ignorance but I cannot find anything in the IPLs that show that a 350 has removable transfer port covers.

I may be showing my ignorance but I cannot find anything in the IPLs that show that a 350 has removable transfer port covers.

The older 44mm bore 350's don't have removable transfer port covers.  The 45mm saws have what's basically the same cylinder as a 353.  The part # for the later 350 cylinder is almost, but not quite identical to the 353 cylinder #.

These saws also have a dished piston to lower the compression (to 'widen' the performance 'gap' between the less expensive 350 and the more expensive 'pro' 353).  The 353 piston (OEM or Meteor) can be used in the 350 to raise compression.

For some reason they never updated the cylinder drawings in the IPL's for the newer 350's with the 353 cylinder...


353 IPL:

http://www.husqvarna.com/ddoc/HUSI/HUSI2004_AAaa/HUSI2004_AAaa__1062544-66.pdf

353 cylinder part # is 537 25 31-02.
353 ring part # is 503 28 90-11

Later 350 IPL:

http://www.husqvarna.com/ddoc/HUSI/HUSI2006_AAaa/HUSI2006_AAaa__5449075-01.pdf

Late 350 cylinder part # is  537 25 30-02
Late 350 ring part # is 503 28 90-11

OK I understand, I was looking at the IPLs and they do not show removable TP covers same as the x-torq saws. They are there but HVA does not intend them to be removed so do not show them as individual parts.

Given that Threebond, Hondabond, Yamabond, Dirko or LocTite 518 should do a good job of sealing them when reinstalled. Use a small paint brush like used for plastic models to get a thin even coat without getting the stuff into the transfers.

That would make sense, I wondered why there was no indication of the covers on the ipl. I'll give it a try when I get the last few parts. I'll try to get some pics of the finished cylinder also. Thanks.
