That is a quite low exhaust port timing. Some of the Ryobi 31cc engines that are similar to the Craftsman 32cc also have a very low port timing. Raising the top of the exhaust port until you get a 150 degree port timing should make a nice power improvement. With better exhaust port timing you will probably notice that a larger muffler outlet on a gutted muffler will work better.

Did you get my PM about the Stihl 65cc Four Mix engines that I have?
