Well THEY didn't show up for chat..(plumb disgusted with bcs).. and thats all ya gotta say ? I talk too much ? I think you do too... lol ah what do you expect from an ex owner... 

The center thing is a neutral connector of sorts.  Has a copper contact on either end. It’s the “neutral contact connector”.    I had to tear this thing all the way down to replace the mainshaft gears on the transmission, so I had cases split.  

you talk too much bro..lol.

make sure you have a neutral light !!!, if you don't ?..it won't fire the spark plug !. check the kill switch on handle bars, make sure its centered ?, and check for voltage across the switch.

that bent metal thing is for the electric starter area, nothing to do with the gear box area. the large bushing is normally inside the clutch basket from the backside over the shaft, inside clutch basket. the washer is always on the very outside of either the clutch basket ?, or the centrifugal clutch under the staked nut. i'm not sure you removed these ? ( you may have to split engine ? ), but they always go on other engines when you remove both clutches on larger atvs. the center bolt looking thing, i'm not sure about that part ?. but i will study the fich and see if i can see where it goes.
