The choke system has been totally disconnected, and the secondaries have been fully connected. I had the secondaries totally disconnected and the vacuum lines plugged last week and I just couldnt get the car to idle at all until I hooked up the secondaries.

I was getting very frustrated so I decided to hook them up and the car instantly seemed to idle much better (plus the power valve leaking which caused me a LOT of grief).

Anyways, the vacuum is at 9-10 inches now. Is that ok?

I should find a few hours over the weekend to fiddle with it. It seems the more it runs and the more I fiddle the better it gets. We'll see.

Ok, a question I cant seem to find the answer to.

- what is the at idle, or off position of the fuel pump lever under the main float bowl? That has a screw to set it, and I have tried to take all pressure off the lever at idle but not sure if its totally off. That does effect idle.

Just cant seem to get it to idle steadily. Either wants to run at 1600 rpm, or if I turn the idle set screw back even 1/16 turn it then wants to shut off. Pretty sure my outboards are as closed as theyre gonna get at idle. I have all 4 outboard idle screws set at 1/2 turn out (first picture is closed, second is 1/2 turn). The springs attached to the screws help a lot, especially the rear.

So glad I have it running now. Took it out a few times today, but it still isnt running right.

Idle is inconsistent. Sometimes it will idle at 1600, then Ill rev it and it will drop to 600, then after blipping the throttle it might go back up and settle at 1000. Seems to have a mind of its own.

I have been fiddling with all six idle screws but mostly the main throttle screw. All six idle screws are about 1/2 to 5/8th turns out.

Once today it just coughed and quit right out of nowhere, and still getting some dieseling after shutoff, but not every time.

Getting closer though

Btw, at about what vacuum should the secondaries open?

Revving the throttle in the driveway up to 4500rpm or so Ive never seen them open.
