IIRC, the switch situation is as follows:

'83.5 - two switches.  One at idle position, one for full throttle
enrichment

'84 - one switch. Full throttle enrichment only

'85 - no switches.

What you're seeing is how it should be. I suspect that your irregular
idle is a function of a failing/failed idle stabilizer.
