Hi, just thought I would share some of my info,   I am restoring an old airplane(pic included) and am amazed how many aircraft nuts/bolts   an fittings are used on my europa, if you
really get stuck on finding a bolt go to  áircaft spruce catalog.   I have attached  a pic of plane from 4 years ago,  it is  almost finished now, lots of hours into it already. Mike.

You are very lucky to have a good PO! Not many people would go through the trouble of measuring bolt grip lengths. I did so I have an appreciation for what that entails, but I’ll let whoever buys my car decide whether I am a good PO or not.  :)

I know you’re not finished with your plane yet , but I’ll congratulate you now. I can believe it was a big undertaking!

  Mike,  nice project .  I hope you also fly .  What fun is it just to build.  I soloed after 14 hours but gave it up when 9/11 closed our air park. ☹️  A friend of mine built several Rv 4, and I was looking into the Christian eagle.
   Well getting back to trying to finish, I spent the day on arts and crafts. Going back to fiberglass work on some ducting. Sanded and formed my crashpad and fitted some of the original plastic to get the thickness correct. I’m going to glass over this unit and use it as a mold.
  Sandman, working on those grills also. Another project was it front bonnet interior catch leaking water into the cabin area and rusting out the heater.  I used a aluminum block and cut a valley into it and since it’s solid , no water problem.
  My headliner rails were also hung today, I’ll be sore for the next few days. 😂👍👍

  Turbo , no that’s the original padding covered with a thin foam. Sanded and formed to coat with glass.
I’ll use it to make a mold then send it out to ,” Just dashes “ in California or try my hang at covering it with leather.

   Checking the operation and fit of the ducting , not pictured,  will be to add a flex tube to the two side vents in dash . The airflow test from the fan unit was equal to that of a modern car. .  If I went with a radio I would have had to adjust the water catch angle better but still doable.  Another addition will be a close out planet to clean up the area and create a area for a drop down door for the electrics .

  A long awaited day arrived with a package from Ultimaguy .  My intake and Weber 40DCOE 8 carb.
As usual I had to clean it up a bit. Yes it’s shiny.  Roscco gave me a lead on parts supplier on the Weber. Rebuilding will be a first , so I’ll have a few questions about this subject.
  Just seeing what’s involved so far is to modify
the routing of waterline .
  I also trimmed the header assembly to accommodate the intake flanges, nothing excessive. The thickness of the two needed a little tweak. Then I’ll wrap the header and fit a muffler.

wow, you've been busy polishing that!!! I found that my Else one is very badly matched to carb so I'm going to have to blend that in before final fit

  Thanks, it took about 4 hrs total time . I should have had it done sooner but I sodablasted it before sanding .  Sanding with a 36 grit on a high speed grinder. Then I used a course file to all the high point and seems . Then hitting it again with the grinder.  Back to a medium file using cross and draw fileing.
 The rest was stepping up sand with 80 / 120/ 220 / 400/ 600  . Then take it to a bench grinder with a polishing wheel 6-8” will do  green rouge   This will polish it up and show the scratches. With that said you can do this step after the 120 grit just to see where to sand out with a heavier grit if needed.

  Spray it with high heat clear afterwards.

  Today I worked on my first Weber DCOE carb . It is an amazing carb, so adaptable and the fact is was built years ago amazed me. While tearing into it and watching YouTube videos I said this was one one the cleanest interior carbs I’ve ever rebuilt.  I documented the jet sizes, mixture screw turns , and choke size.  I did find some damage to the tip of one tube . Pic below.  Some parts needed are some screws and the throttle bracket assembly and that tip of course.
  Ross answered some of my questions about blocked holes on the intake side and the huge 1/2” hole used as vent or overflow of the float chamber.
 If anyone has some ideas of tuning it to a stock , low compression engine with a mild cam or just keeping it setup this way , please comment.
Thanks

Good job cleaning up your carb!

Brass spindles are very fragile. They are prone to twisting. Newer models were upgraded to steel spindles but replacing them is nontrivial because you have to drill a hole in the new spindle for the accelerator pump (IIRC) and the butterfly screws are staked. Be very careful with them and make sure they are straight.

On newer models, the plate between the the two throats has large hole in the center, about 3/8”. Somehow, it keeps fuel from leaking out there. You might consider modifying you’d.

   Thanks BDA,
 Several videos mentioned the screws being staked and will be on my parts list to buy.
It looks like the tip 11.5 on an f2 tube can be replaced. I have not tried to in screw it, but why would there be a hex nut pattern on it.

  I’m not following you here , but I’ll look into it at the Weber supply site JB mentioned a way back.

I was also notified that I need a mechanical advance on my distributor.

More to research.

The hex bits are main jets.  The size is 115.  It is a push fit, no thread.  The hex is to allow you to twist the jet to facilitate removal.

The plate I’m talking about is shown in your last picture between the throats. I don’t pretend to understand why the hole works, or even that it does. I’m just passing information I received when I was having a fuel drip and it seemed to work. It is a fact that new plates have the hole.
