And before anyone bags me, YES.....I have tried searching for the answer, but I'm either typing the wrong question, or the search thing is stuffed.

So.......is anyone able to simply tell me what type of carb a 65 Formula S is meant to have. ?
Carter AVS......but what number ???

That's all thanks.

On a 65 Formula S;
3853S manual transmission
3854S automatic transmission
 
Not to derail from the OP question but since it was answered:

What is the physical difference?
I’m assuming either jets, metering rods or both?

AFB small opening with velocity valve, brass idle adjuster. Auto carbs are significantly different than 4 speed carbs, different primary boosters for one.
