EMPI has redesigned and manufactured a new version the original Kadron Solex H40/44EIS carburetors, manufactiured originally by Brosol. They are very new to the industry. We have been testing them on our own personal cars, and found them to be of sufficient quality that we are offering them to our customers as a less expensive alternative to the original Brosol carbs, with the understanding that there are still some bugs that may need to be worked out.  No warranty is offered with these carburetor sets, aside from what the manufacturer may or may not offer.
