Lots of idle problem threads in the Garage, but I think this is a new one not previously covered:
1. 1974 1.8 L-Jet; regular points/condenser and dual port vaccuum cannister.
2. Runs flawlessly and reliably; idles about 1000 rpm at startup
3. Just recently, when at a stop, the idle drops back to only 1200 rpm instead of 1000.
4. If I engage the clutch just a tad the idle goes back down to 1000 and stays there (until the next stop).
I've checked the throttle spring and such. Maybe something with the vaccuum canister or some other little demon hiding somewhere?
In advance, thanks for your knowledge and insights!
