Corolla Aisan Carbs

^^^^^By looking at the vacuum secondaries, it appears the vacuum line is directly connected from the diaphragm to the secondary throat, my opinion it shouldn't be a problem if you fit to an earlier rolla, simply because there is no other way it is connected. I'd just block off any unnecessary lines on the carby with vacuum block off's.

 

Oh and haven't forgotten about the jet sizes,

 

cheers!

There are many variations of the 3k carby venturi size.

19,21mm were common Pri sizes

24,25mm were common Sec sizes

All were mech secondary’s with a air valve in the sec venturi.

The 3kb had different sizes again sorry I cannot recall the sizes.

Interesting early 3k carbys all have 21mm pri and 24 mm sec and have smaller 6mm throttle shafts and later ones run 8mm shaft.

Dyno shows no difference between the 24mm sec and the 25mm sec.
