Thread: Carb overflowing fixes/failsafe

On an old suzuki with float bowls like ours (without an overflow feauture) I retrofitted bowls from a later model with them. Now if a float sticks and overflows she does a little wee out the tube and NOT down the cylinder and washes out the oil and bearings, cams etc.
Can the same be done to the bird? Is there a compatible float bowl with integrated overflow out there? Could they be brased in up to the appropriate float height plus say 3mm?
As I think about it we also have the petcock issue and its vacuum hookup which is again a potential fuel pathway to the cylinder. Any smart fella have a redundancy solution here?
Ideas welcome as although mine doesn't leak into the oil the mere thought of this makes me sick.

You could build a separate chamber that is in a visible location. Put the supply line to the carbs at the bottom of the vessel and the vacuum supply at the top. then you could check the vessel just before you started the bike for any fuel in it
