Generally they don't close down. They burn out is what they do and as they do the resistance goes up giving weaker and weaker spark. Working from memory I believe the spec is 11K ohms for a good one. My thought was if you had weak spark it starts fine with a good dry plug and then as soon as it miss fires the plug starts to get wet causing another miss fire and then you flood right away due to weak spark.
How is the ground connection under the coil? the old intruders from '87 had a problem from the factory with a bad ground connection. We would take the new ones and make sure the paint was sanded off right under the coil mount to make sure they had a good ground or they would have a bad idle.
The only other bizarre thing I have delt with on flooding at idle is when the o-ring around the needle seat doesn't seal (Item #21 on ron ayers carb view) It is not noticable at higher rpm but it causes a high fuel level and richness at idle.
The question is, is it truely rich, or is it looking that way due to bad spark? If it is truely rich then chase the fuel/carb demons, if you have a spark/engine issue start with the electrical & engine compression route.
Your wife has a savage too doesn't she? have you tried putting your ECU on her bike and see if it does the same thing to her bike? Bad ECU's can act funny.
