I don't recognise that carburetor on your white 5 hp Bob. Is the gasket between the carburetor and tank actually a fuel pump diaphragm, like on the pulsajet? If it is, you will need a new one, and no messing about with gasket goo. If it's just a simple gasket like on the vacujet, I tend to put them back on with a bit of non-hardening goo if they are only moderately trashed (no breaks anywhere, just some surface roughness). However I'm a notorious cheapskate. If you goo them, you'll destroy them next time you take them off, so it's only a temporary solution.
