Have a quick Q: I set my floats for 11/16" from flange to deepest part of the float (upside down on the bench), but thinking that these aren't level on this manifold, but at a slight angle...so...wondering if anyone has notes (since the supplement has zero in-depth info re the carbs other than using an A refresh kit at 12K miles and a B refresh at 24K miles...) on what the correct setting should be, with the body upside down, the floats compressing the valve naturally (ie just the weight of the floats closing the valve) or is 11/16" the right value to use?
and thackerys are set for 70 thou between the coil. carbs move very slightly; checked whilst running by shooting ether at the manifold junction, and the engine did not change rhythm...so, I know the viton o-rings and seal at the secondary throttle manifold is air tight (as are the throttle shaft seals...did the same thing...no change in engine rpm or tone...)
Full disclosure, to get to that number, I did have to slightly bend the tab towards the valve to raise the float up to that value. Should I just have left things alone?
TIA from a stromberg/tc noob.

Bryan, I've never seen a discussion of that for the Strombergs. Lots of discussion for Weber float level. Maybe a question for Joe Curto? Please tell us what you discover.

will do. On the list (which keeps getting longer...the more I do...) of things to investigate.

I' have them at 11/16ths...the suggestion from Joe was to lower it (upside down, which raises the level) to 5/8 (only a 1/16 difference). That tracks with some things I've found through searching through the web.

I know this is an old thread, but just wanted to add some info to the discussion.
The Haynes carburetor manual provides a float height setting of 16-17 mm (.629" - .669") from body flange surface to highest part of the float. That is roughly within the range discussed above, so no real news here, just corroborating evidence. Incidentally, mine are set at 16 mm with no complaints.

I've been running with them set as above for over a year now...and, except for the throttle shaft seals and the piston/needle O-ring (which means I fill the dashpot every day...;)), they've been running just fine, sparker insulators are a nice tan color, and the overhauled OEM dizzy with the pertronix conversion works a lot better than the replacement did. Enough oomph when I put my boot into it for my taste, and a nice growl out of the back end.
(see Steve Veris' note about repopping the throttle shaft seal tool as noted in the TC supplement. I think this winter, I'm going to pull the carbies off again, strip all the way down (last time was as far as I needed to clean them up to get them running but didn't do the ultrasonic soak or what have you) and replace ALL the seals and gaskets after a good ultrasonic clean and such. I have a stock of rebuild kits, a few sets of the upgraded floats, and, a tool I made for the float height out of 40 thou aluminum sheet, and with the shaft seal tool...will be good to go.
