Any search for the ideal 2-barrel, progressive down-draft carburetor would surely end with the DGV Series. look no further for versatility, wide adaptability, easy installation, low initial cost, trouble-free maintenance, excellent drivability, increased fuel economy and improved performance. Designed for engines displacing 1200cc-2300cc,  the DGV Series carbs feature diaphragm type accelerator pump circuits and models with manual, water or electric choke actuation. The DGV also has a power valve circuit to facilitate low vacuum running conditions.

Greater improvements in throttle response at a slight penalty in fuel economy can be achieved by using the 38 DGAS synchronous opening model. This is a high performance alternative to most any DGV applications.

Electric Choke  

22680 056 DFEV

Water Choke

22680 070 DFAV



The DFV Series offers the same increased performance, economy, drivability and excellent values does the DGV Series. The basic design of the DFV carbs is that of the DGV Series. but as a mirror image, with the primary and secondary barrel position reversed in the body While the throttle lever in the DFV rotates in a clockwise motion it rotates counter clockwise in the DGV. The DFV also features a power valve circuit to facilitate low vacuum running conditions-perfect for long duration, high output situations. You get the same value, parts availability and durability as with the DGV in a carburetor suited for your needs.

With its central float chambers, full calibration capabilities, compact alloy body and wide variety of available sizes, the IDF Series has been and continues to be the winning choice for a synchronous, 2 barrel, downdraft carburetor. The IDF features diaphragm type accelerator pump circuits and ball bearing throttle shafts. When used with an adapter, the IDF will replace the Solex 40 PII carburetors used on many Porsches. The IDF is ideal for use on most opposed-cylinder engines, or on engines using IR designed intake manifolds. The IDF offers relative low cost for performance gained, the IDF is hard to beat.

REDLINE developed  the IDF XE Series carburetors, for use in extreme or severe environments. Complete XE carbs include: Extended Emulsion Tube Holders and Adjustable, Spring-Loaded Accelerator Pump Actuating Rods. These XE carburetors  are built to Redline specifications.

To update or convert early IDF carbs to XE specifications, we also offer the XES Kits, which include: Double-Sealed Throttle Shaft Bearings, Extended Emulsion Tube Holders, and Heat-Insulator Mounting Blocks.
