Just cannot get the jet to come back up to rest on the front carburetor after I pull the choke on my tr3. I am using cork glad washers I got from Joe in NY and perhaps they are too large and placing everything in a bind as the jet slides back? I have checked all the pivot points and the preload on the arms of the linkage and believe that to be working. I have even undone the leakage after pulling the choke to make sure the problem is at carb. The jet is polished, but will not return comfortably. If I drive the car the jet will sometimes work its way up, but when it does not the mix is obviously too rich. Anybody else have this problem?

Are your return springs in good condition? Sometimes with new rebuild (new cork washers, etc.) you need to put slightly stronger springs in. I have found that the strength of these springs varies with suppliers.
If you have a jeweler's cloth, you can polish the jet to make sure it is smooth as possible.
I have also read that some people put a touch of vasoline jelly or a drop or two of sewing machine oil on the jet.
And, did you soak the cork washers at least 24 hours in light oil before installing them? This makes them a bit more supple and helps to cut down on the friction.
You have probably thought of all this already, but I thought I'd respond from my own experience.

SP - when I got my TR about six years ago, I had the same problem. After lots of troubleshooting, new seals, etc. I discovered the jets were actually bent.
How the heck you can bend a jet is beyond me - but when I rolled them on the table, they "wobbled".
Got new jets. All is well.

In addition to all of the above, people sometimes stretch the spring inside the jet in an attempt to stop the seals from leaking. The stretched spring put more force on the seal, which in turn increases the drag of the jet moving through the seal.
If you don't know the history of those springs, I'd replace them as well as the return springs.
Another point, all of the pivot points are supposed to be kind of sloppy. I have seen people insert bolts or flat washers, in an attempt to reduce the 'slop', but that usually causes problems.

Well it looks like I fixed it. I must have had it apart 6times. I end up with a different jet and a stronger spring, so I am not sure exactlywhat fixed it, perhaps both. I tried those O rings thinking they would put lessdrag on the jet, but they leaked, but again they might have been OK because thelarge cork washer was bad and before I was done that was replaced also.
