Responses in no particular order...

Andy -> My garage leads directly into my basement / psuedo shop; carbs are stored there where it's climate controlled

Dominic -> If the PB Blaster soak doesn't free it up, mebbe I'll ship it to Hesperia for you to hammer on it

RTS -> Nope, no ultrasonic cleaner access of which I'm aware

WHITEDART -> Ummm... yeah, pretty much; the more crap I'm seeing in my carbs, the I less want to leave it to chance they'll be good the next time I want to run 'em
