I'm about to embark on a Merccarb rebuild, soon.

I plan on immersing the disassembled parts (minus the plastic/rubber ones) in Berryman's B-9 carburetor dip.

My question is how long? I've read several threads that recommend immersing for 24 hours. However, the mercruiser manual states in a caution note: "To avoid damage to carburetor DO NOT leave carburetor in immersion type carburetor cleaner for more than two hours."

Is 2 hours long enough? Am I misunderstanding this caution?

Thanks
