150T, and the itty bitty exhaust hole?

[Patrick62]

I ordered the 150T this week, and it arrived at the store today. I got a chance to look the little guy over. I am way impressed with the quality for such a small saw. Curiosity got the best of me and I ran that screw off to peer into the muffler.

You gotta be kidding me... that itty bitty little oval hole is supposed to let this thing breathe? I know it is only 24cc, but a hole maybe 3/16 by 5/16 ??? huh?

I will get started, and play with it a bit, but there is a STRONG possibility that it is gonna get that opened up a bit, like all the way to the size of the area in question.

Open it all the way. The saw will have better throttle response, start easier and hold more rpm in the cut. Bump the timing 4-6 degrees as well. They’re good little saw once the muffler is opened.
