Chainsaw Repair

Buying the 353/2152 top end really doesn't offer any improvement over what you have. 2153/346 is the only route to go if you are going to replace it.

But........before tossing the current cylinder try deleting the gasket and doing a muff mod. Those cylinders actually run pretty good, and you might be surprised. As you already posted, it's real close to the 346OE, and the difference is not huge at all. Not enough to replace a perfectly good cylinder IMO.
