Sorry about that, I don't know when people are using the search feature. The member that has the compression release has not posted in more than a year. I have made an attempt to contact him and I am waiting for a reply. As soon as I hear something I will let you know. I hope we have not lost him as a member. I too would like a compression release because of my right knee problem. He complained of oily gook at the release on the back side of the cylinder. He might have bad jetting or wrong oil mix. When I was a kid all two strokes had 2 spark plug holes in the head. Most guys would have a compression release in the second hole and use it as a brake. This was back in the early 70's. Does anyone remember them thar days?
