I have a problem with my '77 Peugeot 103s idle. It dies at traffic stops (my brake light isn't bad). Now the strange thing is when I play with the idle adjustment screw (at idle) I get the following results:
Engine barely runs then as I ever so slowy tighten the screw, bam it is screaming and revs up high.. Back up the screw a tiny bit, then back to chugging, choking, dead. Even with the idle set high I still stall out at stops. The weird thing is that other than the idle issue it runs great! Full throttle and it doesn't skip a beat. Plug is not fouling either. Just this damn idle.......! Any ideas??
