Skip Patnode 67 Duetto Norfolk, Va. I discovered another method of adjusting twin Weber Carbs: 1. Make sure the throttle linkage isn't holding the throttles open then back off the idle stop screw (ccw) and make sure the rear carb throttles are going completely closed. 2. Back off the balance screw (ccw) and make sure the front carb throttles are going completely closed. 3. Turn the balance screw (cw) until you can observe the front throttles just starting to open then back it off until they are just closed. This takes a little finesse and a good feel. 4. Turn the idle stop screw in (cw), start the engine and adjust the idle RPM. 5. Adjust the idle mixture screws as far lean (cw) as possible and still maintain a smooth idle. (I screw them in a little at a time until the engine misfires and then back them out 1/8th turn) 6. Adjust the idle screw for about 2000 rpm and observe any roughness. By turning the balance screw very little one way or the other you can eliminate a lot if not all of that roughness. (If you extend the firing order 1 3 4 2 1 3 4 2 you will notice that the engine fires the front two cylinders then the back two. If the carbs aren't both adjusted the same, the different power output can cause roughness). 7. Reset the idle RPM and double check the mixture settings. ------------------------------ Date: Fri, 27 Nov 2015 10:26:14 -0500 From: "skip" <[email protected]> Subject: [alfa] Alfa: Weber Carb Cars Alfisti, Does your Weber engine not come back to idle readily when you release the throttle? Does it "Chuggle" or lurch at low speed, partial throttle cruising? Does it backfire at partial throttle deceleration? Mine DID. I discovered that my Bosch distributor springs were not pulling the advance mechanism back the way they should which caused the timing to stay advanced longer than normal and allowed the timing to hunt at 2500 to 3000 rpms. One remedy if you don't have new springs: Take the distributor apart and under the advance plate are two screws that hold the spring arms in place. You can loosen these screws and adjust the spring tension. I have no way of knowing what I have done to the advance curve but I do know that I now have two cars that drive great and come back to idle like they are supposed to.
