Timing will probably be a little too far advanced.

R your lean on fuel if only mid rpm up up the main jet a size or two. What rpm are you pouring on the throttle and hearing this?

either too much initial timimg,, or the advance curve is too quick..

I do not know if they still put them on during that year but, in 1988 I bought an flstc in Wisconson and on the way home to LoCal somewhere on the Colmbia river gorge my VOES switch went south. Literally drove down the shoulder for a hundred or more miles when approaching any hills.
