    I've seen plenty of people ask questions in the past about this platform. This thread is a place we can put our collective knowledge to better help those in need.

    Common issues I've personally seen:

    Plastic boot clamps break causing the saw to run lean and in cases score the p&c.

    Easy fix/way to avoid: Buy the metal clamp style, inexpensive way to get added protection.

    Loose muffler bolts causing the case or top plastic to be damaged.

    Ways to fix/avoid:
    Run the saw for a couple minutes shut it down, then snug the bolts. This in most cases will work.

    If problems continue use a small amount of loctite. Many kinds of loctite available I've used the red kind with success.

    Parts compatible swaps:

    On this platform there are plastic handles and metal. These can be swapped back and forth with no modifications. This goes with any and all parts. If you wish to upgrade/replace the top end on your 340/2141 or 345/2145 to the 350/2150 all you need is the riser block from a 350/2150. No modifications are needed. Please note there are 2 top ends that belong to the 350/2150. Open port is 49cc and closed is 51.7.

    These saws are quite capable,light and take well to modifications. The 353 and 346 top ends can be replacement options for this platform. And if you're from Iowa the 359 top end can be used with lots of work.:msp_biggrin: Carb swaps are simple they come with Zama and Walbro's stock. You can use intake boots from 357/359's along with other models.

    I hope this information helps someone. Add things if you know anything I missed.

    Great Info, Thanks!

    I have a 340 that has been a great saw for many years but recently its been acting up a bit, I'll check the things you mentioned before I move on to other things.

    You would'nt know the part # for the Riser for a 350 conversion?

    You can find a wide selection of part lists on the US (+ some other ones) Husky web-site, and at least on the Canadian Jonsered web-site.

    I'd list them but I'm currently at the zoo. ST can fix you up.

    He needs the shorter 346 head bolts.

    Yes, it is the 353/2152 cylinder, with a "dished" piston, to take the power output down a little (less compression).

    The muffler bolts from a 288 xp with a small drill and tap job take care of the muffler bolt problem. I have done two in the last month, one on a brand new A/M topend for a 2150 , and one on a 353 that had lost a bolt but it had not ruined the cylinder yet. both saws didn't see thread locker and they are still as tight as the day they were torqued.

    It's obviously best to avoid thread locker. Great option here. I've used heat resistant gasket sealer but that was because my tap and dye set was misplaced.

    I started this thread because most people don't realize the potential of this platform. It's an outstanding design that can be made into a lasting firewood saw.

    I have had two where the bolts backed off or fell out of the bottom of the saw. It caused a air leak.

    Those saws likely are the best "homeowner class" chainsaws ever made! :msp_wink:

    I'd be happy to run one over a 290 or any other home owner saw of any brand.
