I have Dellorto 40s on my car (1.8L). During my rustoration over the winter I went ahead and rebuilt them and re-jetted them. The driver side works perfectly, but the passenger side has what I am assuming to be a float problem.

When the gas flows to the carb it just gushes out both throats and I can't figure out why. I have had the carb apart 6 or 7 times now, but can't make it better. Here are the things I've done already...

1)Tried every combination of old and new needle and seat. (The carbs never had this problem prior to the re-build)
2) Adjusted the float - I can blow in the inlet and with light pressure on the float it seems to stop ok.
3) Checked all the gaskets / seals
4) Tested the float, it floats like a cork
5) Ran my fuel pressure down to 1psi (normally it is a 4psi)
6) Inspected everything and saw no debris or dirt anywhere. (they were cleaned in a parts washer during the re-build)
7) Once it is assembled I can hear the float moving freely in the body.

Any other suggestions. What could it be? I'm stumped.

You must set the float height at 6mm off the top when the needle starts closing, not when the spring of the needle is loaded

This is how I, set Dell floats, you can try it, unless you have a better way?

I, hold the top plate sideways, with the float pivots to the top, now the float will swing back and forth. I now swing the float till it just touuches the needle, you can swing it to far, the weight of the float alone will load the needle spring, so just till it touches.

Now to measure, I take a post it pad, I think there 2" square, I take off as many sheets as needed to get the size required, in your case 6mm or .236".

Holding the top plate as previously suggested, I slide the 6mm thick post it pad between the float and the top plate adjust as needed, carefully.

Here is a link to a Dell parts guy, he is currently having a 4th of July sale, floats around $24. He also rebuilds Dells $100 apiece, I've been told he does good work.
