Holley sniper EFI motor suddenly revving uncontrollably when I blip the throttle
UPDATE:
Removed TBI from intake. Could not get secondary plate screws loose, was afraid of stripping them, so gave up on that.
Put an extra turn in the secondary spring and reinstalled. Still hangs open when secondaries come in.
Tried an extra spring. What I had was not strong enough.
The photo shows a temporary solution: filled the slot that secondary linkage is in, this forces the secondaries to close with the primaries.
It is working and is not binding, but I need to find a more permanent solution to block off the slot in the secondary linkage. What you see is a short self tapping screw.
I'm Thinking a grade 8 machine screw and a nylon insert nut, as long as they don't bind on anything.
