I have this 97 warrior that was running and just died, no compression, I pulled it apart and the exhaust valve isnt closing all the way, It appears the rocker arm isnt coming back all the way, preventing the valve from closing. It doesnt seem to be a problem with the cam. I put a light in the head and at top center I can move the cam between the valves like it should. The rocker arm just seems to stop short of coming back, leaving pressure on the valve spring. I am unable to see what is stopping the rocker arm. It does not appear to be the cam.??????
Any thoughts???????
