carb numbers ending in zero

[SavingTheBird76]

Anyone know if zero is an odd or even number,lol?
Anyone running an original carb,with a number,ending in zero?
I'd love to know where it was originally used.
Anyone know the real difference between 4 speed and automatic carbs?
More vacuum fittings?Different tuning?
Thanks.

Zero is even, automatic cars use vacuum to shift.

Cliff Ruggles knows all about these carbs. He lives in Columbus and he can help with your question.  If anyone would know.  He would!

Zero is neither odd nor even.  It's a place holder.

Zero is neither odd nor even.  It's a place holder.

For marking purposes zero is considered EVEN, yet not a number and a place holder as stated.  In binary numbering, zero is considered even and a 1 is considered odd. Therefore, the numerical designation of zero is only considered even upon it's use.  But it is considered a place holder in mathematics.
