We prefer using only factory Solex Brosol Venturis when servicing Kadron carbs.  Venturis are available to match each and every engine combo.  Whether you are running a stock 1300 or a wild 2 liter, these venturis are the best bet to get the most power out of your engine. The 28mm, 30mm, and 32mm are genuine Solex parts. SOLD IN PAIRS.

Here are some recommendations:

1300cc's to 1641cc's: Use 28mm venturis

1679cc's to 1955c's: Use 30-32mm venturis

2 Liter and up: Use 32mm-36mm venturis

For higher RPM engines, 44mm throttle bodies coupled with 34mm machined venturis work exceptionally well. We can machine them out even larger for racing applications. 

The larger venturis will only breathe as well as your intake manifolds, cylinder heads, and exhaust system lets them.

Note:  You WILL need to change your jets when using larger venturis. We can also supply jets to match every combo.
