Need some help adjusting my decompression lever freeplay. Just got done replacing my timing chain and reshimming my valves, and it noted that I needed to check for 5mm of freeplay on my decomp. lever. (It was always tight - just never realized I needed freeplay) I have turned the adjuster in as far as I can get it, but I still have zero freeplay, and it is so hard to turn I'm afraid the threads will strip if I go any farther. I've WD-40'd the hell out of it and it still is really hard to turn. One thing I'd like to know, though, is freeplay defined as "movement in the lever does not move the decomp shaft" or "movement in the lever moves the shaft, but is still considered freeplay until the shaft actually contacts the valve lifter bucket inside the engine"? I guess I'm ok if it's the 2nd one because I can move it a bit before I feel the shaft contact the valve lifter bucket. Thanks.
