Carburetor Heat Shield


General consensus is that I DO have a carburetor problem: it runs very rich when hot or fuel is boiling in the float chamber and the float valve is unable to seal. Hopefully the rebuild underway will fix all of this, although it has been too hot to spary carburetor cleaner in the boathouse (too much smell in the house).

I have seen several Amphicars with heat shields under the carburetor. They have varied in shape and material. Does anyone have a heat shield drawing (or pictures) and can suggest the best material? I know the carburetor mounting bolts are not very long and this thing cannot be too thick.
