Doing it this way creates the real danger of having one or more of the throttle plates making contact with the throttle body bore when at rest in the idle position. They absolutely need to be resting on their stop screws, not the throttle body bores. The only reliable way to set the resting position of the throttle plates is with the throttle bodies removed so you can verify their position. It is imperative that they not rest on the throttle body bores. If they do rest on those soft magnesium bores, the vibration transmitted to them when the engine is running at idle will damage that bore.
Currently, I know a few of the throttle plates are making contact with the throttle body because they are not resting on their stop screws. So what is the proper way to setup the throttle plates before syncing the throttle valves? Is the only way to remove the throttle bodies? Or is there a certain number of turns on the throttle plate screw I should make once it makes contact?
