Increasing air flow in and out of any motor is going to increase power. Me, Im not a big fan of all this porting, muffler mod mumbo jumbo. Unless your competing in hot saw competitions, just let the saw cut wood.

Mike, as you might be aware there are two different mufflers for 330s. The one I rebuilt and use regularly had a muffler with a hole facing in towards the cylinder which I thought was really weird. From there it had a deflector plate between the cylinder and the muffler and basically blew the exhaust out the bottom of the chainsaw. Now I’m no engineer but I switched it over to the one that blows out the side just like most other chainsaws do. I didn’t really feel like I needed to add to the heat that the cylinder was creating by blowing it back onto the cylinder essentially. Maybe my thinking is flawed. If anyone has info on the two muffler designs please advise. As far as any kind of mod, my knowledge and skill level is not there but 330s are not hard to find so maybe it would be a good saw to experiment with.
Thanks homelite 750 , I didn't know 330s have 2 different mufflers both of mine are the same,blows out from the side, but yes they seem very restricted. Right now #2 saw is all apart ,once I get it running I may tinker with the muffler , seems a couple holes in the outer cover maybe, like you I don't have the knowledge.Again thanks
