See . . all this time I thought you were putting up with poor lighting or had a too dark lens in your welding helmet!

Here's a vision aid for small fiddly things - an 'Optivisor'.
Seriously . . . I can now count the freckles on a caterpillars backside with these.
Make sure to get one with glass optics.

   See pic Paul. I found it on EBay and I use it with my reading glasses Under helmet.

  Gavin , I don’t think that would fit.

It's not meant to fit inside a welding helmet.

   I’ll look into it and try to catch up on welding apparel. :welder:

  With the header route duplicated, I have moved on to installing th wrap on the wedge headers and installed along with the intake manifold.  I’ll need to cut return line to the swirl pot . If anyone has the dimensions of the cut required would be helpful.
  I laid out another job for myself tomorrow, rebuilding the Weber carb with the kit that finally arrived. 😀  then I can order parts for fuel lines and throttle activation.
 Electrical board is gathering spiderwebs but will soon be dealt with.
Crashpad needs some more tweaking before covering.
Brake lines need to be fabricated from the master cylinder to the front t section.
Pedal assembly and the plate to the t section installed.
Ac lines hoses fabricated and compressor final bracket installed.
A swirl pot made of scrap parts from an accumulator after I pick up a spool gun for welding aluminum and some 1.25 ,.059 aluminum tubes.
 Adding the thread serk into the block have been tapped out but I still need to research where to set the depth in the cavity.  If I set to the bottom of the hole I can use original bolts, new of course, or set at block height and use shorter bolts.
  Galvin, I may take you up on that offer for some crossflow rocker assembly items.
       So that’s my list.😜
    Tools breaking 🤬 can’t win sometimes... at the most frustrating time with hard-to find parts made in China.

It looks like you’re really starting to make some headway, D’man!!  :beerchug:

  It took all day now the Weber 40 is rebuilt. I did not change out the throttle shaft bearings because the plates snap shut nicely and I did not order new screws for the plates.   I added the vent hole on the plate as BDA suggested a month ago and was pictured on there sight. The gasket guided the hole location.  It needs a few little items like a linkage arm and maybe a different fuel inlet. The trumpet side also needs a filter and the bits to hold them in.
  I noticed two untapped bolt hole on the lower side of carb, has anyone used them to secure a heat shield.
  Another shopping trip will be to find a silencer to fit under tray, or I’m open to a vendor.  I have been saving a heat shield that will be perfect over it.

Heat shield: https://www.piercemanifolds.com/DCOE_DCO_HEAT_SHIELD_99003_015_p/99003.015.htm

Edit:
The brass throttle spindles are very fragile but replacing them seems very nontrivial since all spindles need to be drilled for the accelerator linkage arm. You should make positive that there is no twist in the spindle. Given the fragility of the brass spindles though, I would suggest you replace it with a new steel one and preclude that possibility in the future.

Edit again:
If you replace the spindle, I would advise replacing the spindle bearings with new sealed bearings. If you do, I would advise you to continue to use the leather seals.

40DCOE?  That's fine when it's a pair of sidedrafts.  Use a 45DCOE for a single sidedraft.

 Thanks JB ,  Yep , a 40DOCE8 .
  Another lotus Europa owner said the recommended the same thing and the Weber sight put it at just inside the cc usage . This came with the manifold so I’ll use it at least to start the car.
  The Weber 40/45 service manual( See pic)  listed the 8 for a 404 Peugeot and a Maserati 3500 GT, ( probably with 2 like you said) .  25 and 26 for Renault 8 Gordini which had 2?.
   Hopefully it won’t be hard to swap out later down the road , at this point I just want it to get thing routed and make a little noise.
  I’m still progressing on the crossflow, having the courage to drill out the stripped out head bolts 2ea.
and insert the insert. I have the head on , just with two bolts to check my clearances with the header I made.

   BDA, thanks for the picture , I have enough material to make 2 .

  Been dodging the much needed rainstorms but can do without the tornado threats.  Working on a few combination brackets and heat shields.
  First the carb shield, template made and drilled out, now to trim and bend up.

  Went with a transverse muffler, “silencer” so I needed to fabricate a bracket/ heat shield to mount it on to fit under the rear boot, which it will. Thanks Rosco. I’ll still tweak it a bit more and add a top shield.

Looking good, D'man! I think I would be careful screwing your heat shield through the bottom cover because you'll add a potential leak path (if I understand what you're planning on doing). I would note that the venturi set screws are secured with a tabbed lock plate (it's probably just me but the lock plate on one of my screws didn't do it's job so I threw out the lock plates and used safety wire after that). Given that you'll have a fair amount of overhanging weight on those four little screws, you might want to use safety wire there too.

 Oh no BDA. That was just to show the screws line up. I’m also thinking of using longer screws and adding stand-offs between plate and carb to add even more space between the two.
  I should delete that pic .
 However this is a better way to attach the two. See pic

Nice work!
The more I do the more I find I need to do....
