Re: Port and polishing TB.. I recently started porting mine (with a dremmel). I still have a lot of work to do, but you can see its not all that hard. Just get a sanding/grinding set of bits from walmart (mine cost me $11.96 I think), sand down the big ridge and make it a smooth transition to the mouth. Grind down the shaft the blade sits on a bit, but DONT change the bore size around the blade or else you'll screw up your idle.
