Man that thing is running good.... I have a STIHL 029 Going to convert to the big boar cylinder 49cc I will definitely use a pop up piston and do some mild porting Good video
I have done two ms271 so far and they are running better then new. The sound is even more awesome. I am worried about temp on one but i dont really know how hot is to hot yet. But so far i have had great results.
man that first saw is TIRED.... look up 2 stroke cold seizure and you might then understand why pros always allow their 2 strokes to warm up before running them wide open haha
