Prolonged fast idle on warm-up. Why so many idle screws? SAS1, SAS2, SAS3? 1987 2.6
With the cold setting in my 1987 2.6 liter baby has developed some choke quirks. It cold starts just fine - idle just a little low but stable. As it starts to warm up the idle speed climbs to maybe 1500-1800 and won't drop until fully warm. Linkages and coke plate are clean.
I've read up in the forum and examined the carb diagrams. Why so many idle screws?? Warnings about not touching SAS2 and SAS3 have me worried, and I don't understand what the 'throttle opener' does. Carbs don't frighten me - my hobby car runs dual Weber DCOE side-draughts an I do fine by them.
What exactly can I adjust to get the fast idle to drop back faster?
