John Birrell Posted September 18, 2003 Share Posted September 18, 2003 Can anyone provide the valve timing numbers for a GSR camshaft? I am trying to get a camshaft ground for an EA81 to be used in an Ultralight aircraft, and one firm has the masters for a gsr, but can't easily give me the numbers. I have only been able to get the numbers for a twin carb EA71 engine, and am wondering how close this would be. Quote Link to comment Share on other sites More sharing options...
