Grab each spindle and try to move in back and forth perpendicular to the axis of rotation.  There should be virtually no movement.

There are no bearings.  Often just replacing the shafts is sufficient.  Details can be found in the post previously mentioned.

I think the needles are labeled at the top where it is screwed into the piston. Somewhere the standard needles are listed and you can see if you have the correct needles.

If there's play in the spindle/butterfly then could you have an air leak at that point ? I've not had enough experience with strombergs to know if what you've described is down to wear'n'tear or adjustment, but if you do have an air leak then that could give an increased idle.

There is clear movement on the left hand carb spindle.  Moving it while the engine was running impacted the idle immediately.

Time for a complete overhaul.  The needles and needle jets wear as well.  Myself, I would also fit adjustable dashpots from a TR6 or TR7.

Does anyone in North America offer a rebuild service?  I have read the Buckeye complete rebuild pages and it does not seem too complicated but I am closing in on the finish line of a 5-year project car and really don’t want to tackle something else right now.

Picked up some lotus service bulletins on the Strombergs.  I posted them on lotuselan.net, but thought they may help others here, too, so wanted to share a link.

topics include jet height, converting to air valves with adjustable needles, and spec clarification

Finally got time away from other car projects to spend time with Lilly the Lotus.  Pulled the carbs and sent them to Apple Hydraulics for new throttle shaft bushings.  Unfortunately they refused to work on them as they were too clean and looked freshly rebuilt and I had not separated the throttle bodies.  Rather than wait to talk to me they left a VM and then returned them via UPS.  Most ridiculous experience I have had with any service I have used on any car.  I will now give Joe Curto a try.  Maybe I need to lather them with some greasy road grime first!

They are just sh*ting you.  They didn't want/couldn't do the work and made up some garbage excuse.  Never heard a bad word about Joe, good choice.
