IT's certainly possible.  People talk about it a lot.  Float levels also.  Pasted a Google link below.

Wish I had some carbs to work on right now.  Send me your carbs and I will rebuild them for free.

Zed head.  Honestly man. Im tired of messing with these carbs.  I had these carbs vapor blasted and rebuilt last year.  They leaked a little out the cold start mech so I sealed them up.  They were good!  And now leaking there again.   Wanna buy old Italian model 18 DCOE 40s?

My carb knowledge is old Carters and Quadrajets and Kawasaki.  Are those DCOE's?  I don't even really know what that means.

STILL!  They have floats, and they might be stuck, and the levels need setting.  Another thing that happens is that a float will get a pinhole in it and slowly fill with gasoline.  then it doesn't float anymore.  It's a sinker.

Like SteveJ said, take a look.  Might find something simple.

I've seen replica carbs used for electronic fuel injection.  I think it's the Jenvey system.  Found it.  The DCOE Heritage system.  https://www.jenvey.co.uk/products/#classic-cars

Sound good.  Thanks guys

Yes, DCOE's

It's basically italian for 2 bore horizontal, IIRC

there are several areas that can leak

Philip might be of help here @240260280

Adjust float level as first step.

Thanks.  Level is set correctly. Using dip stick method

 

I found this.    https://lotuselan.net/forums/viewtopic.php?f=40&t=24632&start=

Guy talks about drilling a vent hole in inspection plate.  Older Italian made webers have solid throttle shaft inspection plates and newer one have a hole.  This has to be it

I found a video that shows the tapping method for unsticking stuck float needle valves.  Requires a special tool.

It starts at about 30:35.

 

Thanks Zed.
