Thanks very much for the details. Right now, mine moves, but with a bit of a hitch. In neutral, and between the two "legs" of gears, it feels (on the shifter) like there is an elevation change between the legs. As in, when moving from neutral point between Reverse and 1st and moving "forward" to the neutral point between 2nd and 3rd, I have to elevate the shift lever slightly.
I am hoping cleaning and bushing replacement will cure this. I have never tried the kerosene trick, so thanks for that.
Will keep you posted.
