Husqvarna 365 Special to 372xpw Conversion & Husqvarna 372xp OE vs. 372 X-Torq. Whats Different?

A perfectly good Husqvarna 365 Special ( 2004 closed port 48mm version ) gets torn apart and built into a Husqvarna 372XPW 75cc saw. It really doesn't matter which version of that saw you start with, Husqvarna 362.365,372XP, AND the X-torq variants. The process is essentially the same. Also Jonsered variants such as the 2165,2171,2166,2172same deal. All the Husqvarns OEM parts came from Ashokan Turf & Timber NOTE: After a bunch of questions, Contact me on Facebook Group "Chainsaws & Woods Craft" or on "forestryforum.com" ( screen name "weimedog" ) if you are interested in the tools I build ALSO Started a "FaceBook" Page "Husqvarna Autotunes Only" for those who want to get into the discussion of CST and the more technical side of Autotunes
