Trying to adjust the valves on my sons 123. Problem I'm having is, I can turn the adjustment and lock nuts till I'm blue in the face and no change in clearance. I'm ASSuming that the valve is turning with the adjustment nut? How do I prevent this? I have two valve adjusting wrenches but not the third (that I'm guessing holds the valve still). If it isn't the valve turning what else could I be doing wrong? I checked the clearance on the first valve and it was very very tight. Just got the car and don't know when the valves were done last. How many turns of the nut are we talking for an average adjustment? 1/2 turn? 2 turns? 5 turns?

Any insight is appreciated.
