EMPI 40K Deluxe Kadron Dual Carburetor Kit — VW Type 1 Dual-Port, 40mm
The EMPI 40K Deluxe Kadron Carburetor Kit is a faithful reproduction of the original Brazilian Solex/Brosol sidedraft carburetors that earned the Kadron name a cult following in the air-cooled VW community. Smoother and more streetable than a Weber IDF or HPMX, with the period-correct look restoration enthusiasts and Cal-Look builders love.
Vehicle Fitment
- VW Type 1 dual-port engines: 1600cc and up
- Applications: Beetle, Karmann Ghia, Bus (Type 2 with Type 1 conversion), Buggy, Baja
- Note: For 1700–2000cc Bus and Type 4 engines, use EMPI 43-4431 instead.
Why Choose Kadron Over IDF / HPMX?
Kadron-style carbs are progressive single-barrel sidedrafts — simpler internally than a Weber IDF and easier to tune for street use. They make excellent torque on stock-to-mild 1600cc engines, idle smoothly, and don't require the constant fiddling some Weber owners deal with. The trade-off: they don't have the top-end potential of a 44mm IDF/HPMX for high-rpm performance builds. For street driving, weekend cruising, and resto-cal builds, Kadrons are hard to beat.

Frequently Asked Questions
- How is a Kadron different from a Weber IDF or HPMX? Kadrons are progressive single-barrel sidedrafts — simpler internally, easier to tune, and smoother on the street. They don't have the top-end potential of a 44mm IDF/HPMX for high-rpm builds.
- Will it work with a stock fan shroud? Yes — unlike many IDF kits, the 40K Kadron kit is compatible with the stock fan shroud.
- What engine does it fit? VW Type 1 dual-port engines, 1600cc and up. For 1700–2000cc Bus and Type 4 engines, use EMPI 43-4431 instead.
Installation
Installation note: Pre-jetted for typical 1600cc applications. Larger displacement or modified engines may need jetting adjustments. A vacuum-assisted distributor is recommended for best part-throttle response. Use the EMPI Pro-Sync (43-5712-0 or 43-5718-0) for proper carb synchronization.
