I am adjusting the valves on a 300D 1981. The problem is, i cannot figure the increments they are using in my manuel. I have asked tree different people including mechanics, i have gotten three different answers. Here is the numbers. I am used to thousands. Intake: 0.10mm-o.0039in. exhaust:0.30mm- 0.0118. Could somebody convert this to the closet thousands, so i can use my feelers gauges, that i understand. Thanks
