A carburetor question for YOU guys

[mharney]

So I have this generic 34PICT3 carb I am working on, it's been lean on main circuit. Everything checks out, but the discharge nozzle is weird on it. I expect a larger ring at the base and a discharge port, not what I see here. Here is the body and the nozzle.

If you have one of these units, can you try to take a picture of yours if it is different? This just looks like it must have had a piece pressed in that fell out.

I just checked my Bocar 34 and an original German Solex 34 pict and they are both the same as your carb.

I took pics and if you want them I can post but they are not of the same quality and there is not enough difference to make that a cause.

Just for the heck of it take a 2 inch piece of fuel line and add it to the fuel bowl vent like I did in my turbo project and see if that richens it up any.

You could also try one a bit longer too.if you have the room in the aircleaner. I didn't have room and that is why I only went with the shorty.

I would like to know since it really richened up my main on boost from 18 to 1 lean full load to 9.5 to 1 blubbering rich at full load.
With just that change of all the screwing around I did to try to get more fuel that is what did the trick.
I went from a 180 main lean back down to a 145 main still rich but enough boost and power to rip both my silicon intake boots and slip my clutch.
I am in the process of installing new super boots and a new clutch before I can try again.

I went and took some better pics......still not great but they do show the piece you want.

Ignore the copper tubing insert.
This is a carb I modified for my turbo project. I inserted a piece of copper tubing around the jet port to try to make an auxiliary vent since I remove the original venturi. It will be retested later once I work out the Bocar first.

I would think that you might see a result with a piece of hose since the theory is that it gives a better atmospheric reference farther away from the venturi.
It is at least worth a try.

I'm looking for a picture of the SAME carburetor Clonebug, but thanks. Yours have the lip I am used to seeing.. This one does not, and I suspect it has lost an insert. The lip speaks for a lower entry into the depression zone at the minor diameter and a draft effect at higher air speeds. It makes no sense to have to elevate the float bowl vent, the mixture should be right with the correct jets.
