My Teapot Boils over regularly on my VR57 Supercharged Sedan when the weather get over 85 degrees.  It actually floods the engine. 

It is heat/fuel related in my situation, and only does it on very warm days.

It is due in my situation to the heat soak after the car is shut off and the fuel in the carb boils over, just like dirt under the needle and seat.

My issue is cause by the modern fuel having a low boiling point, I live at 3200ft elevation, the blower heats up the air in the bonnet, and the heat cannot excape the bonnet when the engine is shut off or sitting in high heat traffic situations.  I have a return lines and a fue;l pump controller to slow the pump at low rpms.

I have dealt with this for years on this car.  I drive it so often that it is a problem during really hot weather, especially when I am running errands, and it boils over after sitting a few minutes.

I have tried every needle seat and different float levels and phenolic spacers.

I have a switch on electric fuel pump and shut off the the pump when it floads the carb.  I have to shut off the pump and hold the gas down to clear the flooding until cool fuel get back into the carb.

My '57 t-bird has the same fuel boiling issue on really hot days as it has a 460 under hood.

Who sells the replacement covers?Sounds like a great product.

  

FYI: They now sell a replacement cover with "O" ring gasket. Allows for removal to service needle/seat without the need to replace hard-to-find gaskets.

One of the things that Hoosier pointed out to me was this.People had a tendency to overtighten the stud in the centre of the top.When this happens the top ends up pulling up on the edges much like what happens when you overtighten the valley pan.The top should be checked for "flatness" as the casting will become permanently twisted over time..

  

Yes, that's the one.

On my engine when I started it in the chassis, I had that problem. I was sure that I had replaced the gaskets on both carbs when I rebuilt them, and I had. BUT, both were leaking. I stopped the engine, removed both plugs/screws and put new gaskets/washers on with a bit of Permatex and problem solved. A bit scary, as I wasn't the one that noticed it. Could've been a big problem.

I believe Jim is talking about the access cover to the fuel inlet needle and seat?

  

Something to also look for/at. With the air cleaner removed, there is a brass screw about 3/4" in diameter that is angled and located on the fuel inlet side of the carb at the top. If this screw comes loose, or if the gasket fails, the carb will send fuel out. This screw is the item that gave the carb the "Inferno" name.

The Teapot is about 400CFM as I recall.I replaced mine with a 390 cfm Holley.

  

Just out of curosity, Does anyone know what CFM both carb types flow?
