Sandblasted
by RazorbackNOR ... December 13, 2010, 02:53:42 pm
Not much progress nowadays because of a meter of snow all over the country.... But a little "behind-the-scenes" work is allways good to have.

Been stripping the old carb I got from the slaughter, the one seen on some of my old pictures, fuel had become solidified, gaskets an o-rings stiff and broke, and there was a serious oxidation on the body. Tried first boiling it in citric acid, didn't do much, got a serious case of "mud" on it, scrubbed it of, but didn't do much for the look of it.

Brought it with me to fork, and got serious on it with a soft sand blaster here. Tht did the trick!
Just got it masked, and ready for a clear coat.

A little polished...
by RazorbackNOR ... November 24, 2008, 11:49:10 am
Unbelivable what a little elbow grease can do.....



Hmm, thinks me needs a newer camera, not just a compact one...




Stone you say Anders....  Shocked

Had it only been just that.....
Upon prying open the butterflyvalve, this came out....

How on earth this have managed to make its way all the way here, is beyond me....

And by the way Anders, this little "hole" on the top here, is this for removing the jet...? doesn't seem to be a hex either....  Huh

Pity I didn't take any pictures of the lower butterflies, one of them was rusted stuck... Have gone over and gotten it back nor "normal" shape again, doesn't look like is any worn luckily.

Don't quite understand how all the things in the carb work so i'll just have to talk your word for it  Wink , and looks loke a hell of a job trying to locate all channels and holes....

Catfood!?? Well the car was stored for several years with the carb and manifold off the engine and sitting in the trunk, so it's not unlikely that a couple of mice has used it as a food storage Wink

Yes, air bleed. I don't think you can remove it as it's press fit into the carb body. Its function is to bleed air into the fuel coming out of the high speed jet E in this drawing:



I like the photos from your house with the Murena buried under the snow! Your house looks nice.

Rusty bits my ass..... How they got in there is anybodys guess, but it is actually catfood....  Shocked Shocked

Air bleed you say....? just looked like they are brass and could do with some cleaning, but removing them seems like it would be kind of hard...

On the down side, me and the wifey have decided to sell the house and move closer to the city, so for now all parts have been placed in storage and the house cleaned.
For anybody interested, here is what it lookes like. http://www.finn.no/finn/realestate/object?finnkode=16253107&sid=xz6fbaetLUR787740&WT.svl=Link.

And yes I know, the Murena shouldn't be like that now....

Nice work Smiley

I haven't noticed your updates until now, that's why I haven't commented - sorry! It's a pity that this blog section is a bit hidden.

Where exactly did you find those rusty bits? Throttle shaft looks good, no wear.

The little hole in the top is an air bleed. This carb has a high speed enrichment device in the secondary venturi: When the air speed through the carb is high enough, the jet can suck out petrol from the float chamber and cause an additional enrichment which is necessary under prolonged full load. The air bleed is there to mix the fuel with a little air to make an emusification. Same principle as with the main jets and emulsion tubes.

Gaskets and O-rings

Seems like time(and other things) have taken its toll on the rummer in the O-rings....






Same as above, just removed from the carb

Here is a first look at the goodies...

Seems rather oxidated, so vil try to have a go at the parts with Autosol and some steelwool.

Just keep posting pictures (nice carbs, by the way!) , - at some point I will find the bug in the forum extension - the pictures *are* there, and as Anders experienced, they turn up when you change into normal forum-board view. (which you do when replying etc)

The blogging extension is very minimalistic, and the blogs are really implemented as standard forum posts, - in hidden foldes in the "General Matra Related" section.

This is a direct link to Razorback's carb Blog as a forum thread:
   http://www.matrasport.dk/forum/index.php/board,29.0.html

I will keep searching for the error - I have already found some interesting blog-related errors in the forum log that I will track.

There seems to be a bug in the blog software so attachments don't show properly, except in certain conditions. I'll chat with Lennart about it... we might be able to find a solution. Until then, I'm afraid you'll have to avoid posting messages with attachments in the blogs section.

Oddly the photos came up when I commented!???

Here is a first look at the goodies...

Seems rather oxidated, so vil try to have a go at the parts with Autosol and some steelwool.

I would avoid steel wool on the carbs and only use a small brass brush. WD40 is great for cleaning old aluminium parts - kind to the metal and able to penetrate the smallest parts. Also useful for cleaning out channels in the carburettor body. Also, I suggest you screw out all jets before cleaning the body. The float chamber should also be emptied and cleaned.

There seems to be a stone caught in the secondary venturi! Good that it didn't make it into the engine...
