The position of the throttle valve is not important on any engine. If this were the case then a cold engine would always be difficult to start due to low compression. My service CD tells me to remove all the plugs, disable the fuel and ignition and then take a reading after 2 or 3 turns on the starter ( M117 V8, a normal compression being 8.5 bars and not below 7.5 bars with no more than 1.5 bars between any 2 cylinders ). It's always worked fine for me on any of the cars I have looked after over the years . . .
