This page is dedicated to the Dellorto carburetor (48 DHLA) and intake system as produced by Racing Beat for rotary engines. Dellorto stopped producing these carburetors in 1992. Apparently Lotus and Alfa Romeo were the last companies to use the DHLA in production. Once they switched to fuel injection, Dellorto stopped mass production. I believe that they still producing spare parts.

Once production of these carburetors stopped, Racing Beat had to stop producing their intake systems that used the Dellorto. Currently Racing Beat has a very small amount of spare parts and are not maintaining their inventory. They are also no longer providing support and information about their old Dellorto systems. However, they have given me permission to place any of their Dellorto related documentation on this site. J

This site contains all of the relevant information I could get my hands on. There are the original Racing Beat documents, information I gleaned from the Net, and knowledge gained from my own experience. Additionally, several people have sent me their jetting, setup experiences, and corrections. I greatly appreciate the time people have taken to provide additional information on these (now old) systems.

If anyone has additional or corrected information, email me (dave@gruntled.com) and I'll update this site.
