Looking For Input, Still Having Issues

Right - so there's your rich problem. That's the fuel bowl vent. Your fuel bowl is overfilling and overflowing. So your needle/seat is not working/your float is fooooked or your pump is hammering out too much pressure. Take the top off the carb and take a photo of the bowl/float and also the needle/seat from the side and directly at the base of the needle/ballbearing and post up so we can see if there's something odd.

Do you own that $20 gauge to check your fuel pressure? I'd certainly want to know what it is. Hopefully, it's just your float needle valve that's bad.

Gently take the top carb gasket off. Remove the float and hold it level.
It looks like the tab that the float pivots on is bent. But it may be just the pic. If the float is sunk in the carb bowl it's time for a new one.
Good Luck.

I just skimmed through this thread, yes from your photo above it certainly does appear that your float is not floating, it's sunk down into the fuel.

Also, from your first video-- is this a crack in your intake?

Maybe just a mark on the manifold... I have a hard time believing you wouldn't have seen that if it were a crack--just wanted to be sure.

I dealt with a similar issue you've described, Only with a 34pict.
I followed VW-resource guidance is resetting the carb to factory baseline- disconnect the throttle cable, reset, then reconnect.
Good luck.

Hi John. On this pic here there are two jets on the right side of the carb body. They are different dimensions on the orifice. I don't recall which one goes in which hole but the threads are the same, hence interchangeable.

I don't have one easily available but someone out there knows.
Did you look at the fuel inlet needle valve?

You certainly found your problem, the float has absorbed fuel which makes it less buoyant, the new one should fix it.
The 2 jets on the side of the carburetor below the choke are the idle jet and the power jet, the idle jet points slightly rearward and should be a .65, the other one that comes out at 90 degrees should be .50.

I will go ahead and post my experience from the last month and tonight as well as it seems to be inline with the OPs problems.

Been having issues with fuel spitting down the throat of the carb and gurgling with my new to me 71 super. It's a 1600 sp that was very well maintained by the previous owner. Has a newer (less than 2 year old H30/31 carb). I got her October 1 and drover her home from Tulsa, a four hour drive nonstop @65-70 mph. When I got home I could hear the gurgling in the carb/intake. Also the fuel in the oil caused my oil cooler seals to go. Also had a few times where it would hydro lock from fuel in the cylinders. She didn't like to start hot either.

So I started checking things. The needle was clean and I added an extra shim for good measure. The carb would continue to spit fuel down the throat after the car was off. The float is the black solid type and it passed the float test in hot water. So I changed the fuel pump as it had a small leak under the gaskets anyway along with the stand and shimmed it per the Bently.

Problem still happened.

So, today a friend of mine gives me an old German solex 30 pict 2 which had the solex float (brown and hollow) which I put in the newer H30/31. I did the float test again and it too passed. I compared the black solid float with the solex hollow float and the weights were extremely different. Lo and behold after installing the hollow float the problem is gone. Hot start issue is gone as well. Cranks and starts easlily the first time, every time now.

Bottom line is I think the fuel we have with the ethanol is bad for the new solid floats if they are allowed to sit for any length of time.

Sorry this post is so long but I thought I'd put it here for anyone else having these issues.
