Hi all

Using the new feature of the forum, I have started a blog about my Weber DCOE carburettor conversion project.

A blog is a personal thing and as such ideal for sharing a project while it's happening. I'll try to amend to the blog whenever I have something to share or document, but I can't promise any specific frequency.

Feel free to comment! - I'm the "blog owner" and the only one who can post in the blog, but everyone can post their opinions, comments, questions etc.

Here's a direct link to the blog:

http://www.matrasport.dk/forum/index.php?action=blog;blog=25

I hope you'll enjoy it! Smiley

- Anders

I've posted a new message on the Weber blog. I now have the carburettors on the manifold, ready for initial testing on the car Smiley

The carbs went on the engine today! Grin Still a bit more work to do before I can fire it up, but at least they are now where they are supposed to be instead of collecting dust in my basement!

I fixed the dipstick tonight. I had to take the carbs off, but they are back on now. Read here:

It's alive! It runs!

Idle is too low, it's too lean in the low end (I think, haven't checked anything yet, but it spits back a bit and hestitates) and I have a valve clicking like mad (I haven't noticed it before?), but they seem balanced and the sound is great! "HrrrrrRRRRRRRRRRrmmmmmmm"

More later...

I took this photo last night after the throttle cable was done:

This morning, I have contributed with an update about trying the larger acceleration pump jets, and experiments with airbox design Smiley :

Just did a quick airbox for you Anders.  Grin

Trying to brush up on my drawing skills.
Just say what more you want on it, and I'll see what I can do. Cool

Niiiiice Smiley

You've mirrored it though... or extruded it the wrong way Wink

I can send you my latest drawing later in DXF (I'm awaiting a delivery of a mounting flange to complete it), but without the complete engine room and engine mapped up, there's not really any reason to make a 3D model. Cardboard and plywood has worked fine for my prototyping... and my 2D drawings of the hole patterns are enough to weld up a box.

But I might have triggered you here... I've got a few drawings of the carbs that you can use to create a model of those...? Smiley

Indeed. The inlet hose will be connected on the side and air will be fed through the original filter assembly.
