Dellorto DRLA idle question Options

[cgnj]

Hi,
what style linage are you using? The crossbar linkage is lots of headaches, not able to return to throttle stops, and unequal pulls can cause the problem you describe. My first step would be disconnect linage and sync carbs, then go from there.

I currently run 34 vents in my drla45's, much better drive-ability on the street. I beleve there are 65 idles.

Good luck

Just curious what fuel pressure you running. Has it been measured. When the car is idling use a mirror and see if fuel is spilling over. Your description also makes me wonder how the linkage it set up. Sounds like 1 arm may not be returning to the proper resting position. If it's off 1/16 of and inch the idle won't come down with whatever . I would like to see a picture of arms on both sides pushing against the set screw.

I don't have a way at the moment to measure the fuel pressure. I think my FLAPS loans out fuel pressure gauges. I'll see if I can get a measurement. Where exactly would the fuel be spilling over?

I'll try to get some pics when I get a chance. I've got the push/pull linkage with the two separate arms the push outwards to open the throttle, and not the kind with the single big hex bar.
