Not sure if you ever resolved your stalling or idling problem? I have a '91 Evinrude 90hp <br />that had the same problem. The manual says to prime the VRO oil tank bulb first and then <br />priming the gas bulb. If you omit or squeeze the oil tank bulb last then the engine is rich <br />in gas and it will inject extra oil which fowls the plugs. Doing this resolved my problem.
