Edelbrock 1406 whistling
Chief,
I checked the choke o-ring, and it looks fine. I removed the whole assembly, just to make sure there were no issues...the piston inside works fine, too.
I used some putty to plug up the obvious holes, and also around the shaft I suspect, but it still whistles (see pic).
Then I started fiddling with the secondary linkage, and discovered that when I sprayed fluid here....
...and especially HERE....
...the idle smoothed out perfectly. I found that if twist this shaft while the engine is running, it takes off like a bat out of hell, running WFO (and scaring the hell out of me)...and, if I spray a mist of fluid across the secondaries...
....the idle also smooths out perfectly, also. Could it be those secondary plates are whistling?
If so, I'm wondering if there is a linkage problem down there; I can't believe that the shaft seals would just "go bad" all of a sudden. And I'm not really sure of how those cams and plates are supposed to be contacting each other in all that stuff...is there a photo or a website that can tell me how they work?
