I just adjusted the valves on my 235. Very easy procedure. 8 of the 12 valves were right were they should be. Four of them needed adjusted. this eliminated the rattle/knock I had at start up and acceleration. Here is a good procedure for adjusting them. This was my first time and I did it in about 30 minutes. http://devestechnet.com/Home/ValveAdjust
