Using 1.8Lt Carbs on a 2Lt
Can this be done, I am looking at replacing the worn out 1800 in my van with a good 2000, but the carbs on the 2lt are shagged and the carbs on the
1800 have just been rebuilt.
What a predicament!!
Thanks folks

Just double check jet sizes (main, idle and air correction) as they did vary over the years.
Carbs did change also, but are fine to swap as Mick said

yes just bolt them on, but in the interest of the survival of the heads, make sure you have at least 132.5 main jets, the 1800 usually has 130 jets
& will be too lean the air correction jets can be 175 or more ideally, 160
& while everybody is reading this, where in Sydney can I get a pair of 135 or 13.5 main jets? I find 132.5 tooo lean for my use.

Just some interesting reading on the subject from type2.com (answer to a similar question)
At 09:00 AM 10/08/2003, you wrote:

It wouldn't surprise me if CB Performance is re-curving the 009's for the
T-IV engine. Weights and springs can be modified to do this. The stock 009
range of 25 degrees is wonderful for the T-I motors. But it must be
modified to give 15 or so more degrees of advance and smoothly through the
range if it is to provide something near the best efficientcy that the
stock vacuum response dizzy will give with stock carbs.

Standard 009 25 degree advance will not match the T-IV needs. 009 modified
to T-IV curve and range will be just great as a compromise. Stock vacuum
dizzy will respond perfectly to stock carbs if jetted stock for capacity,
give faster retard upon shutting the throttle protecting against
pre-ignition, and follow more closely a smooth timing rate best matched to
the engine design. The 009 is a great little R&D platform for racing types
because with springs and files, you can create a custom curve to match a
specific custom motor build.

And as someone pointed out earlier, they are as close to stock for 72 to 74
T-IV engines as anything readily available. Beware, however, that jets and
such must be sized properly for your motor. My impression is that CB
Performance knows this and will jet them properly for a 1700 or 1800 or
2000 cc. If they say they come with universal adjustability for 1700-2000,
well, do measure exhaust gas to determine adjustability. Then buy jets.
Some vendors do send out assortments of jets upon deposit so you can do
your testing, select your jets, and send back the assortment for refund of
deposit, less the jets you keep. Ask CB about that.
I know CB had all good answers and provided all jets and emulsion tubes and
gasket set for me to dial in the Webber Progressive for T-IV's. If they are
putting together tuned packages of dizzies and carbs to fit spec dual carb
T-IV applications, hurray, pay their price cause it's worth it as it will
save you a whole lot of time/money. If you get generic one size fits all
jets and a 25 degree 009, well, you are likely 2 modifications away from
good results. Re-jet and re-curve to fit adds lots of time/money.
