Hey guys. I'm new to this site as well as chainsaw modding. I am a diesel mechanic by trade however I am trying to learn as much about these cylinder assemblies as I can. I see guys porting and decking their engines. I hear about woods ports etc. Here is the deal. I am on the east coast, and honestly I have yet to find a chainsaw engine fabricator. I do not want to take my cylinder to a hack. I am willing to do the porting by myself but really I don't have knowledge nor know how to perform a task like this properly. I hear about squish on base gaskets etc. I guess what I'm asking is. Is it OK to run the 372xpw without a base gasket and if so what am I gaining? Also how is squish measured? And the last question. Does anyone know a engine guy on the east coast? I am a perfectionist and I want to do something right. Don't get me wrong the 372 has plenty of power for what I use it for. I just am a gear head and love to improve things. I switched to the h/decking filter, high top, I modded the muffler but would love to go to a two stroke expansion pipe. Any ideas on the best pipe? Or do I build one?
