If you have a 2 liter engine that runs out of steam due to small carburetors these will wake it up. Same mounting bolt pattern as Weber 44 IDF and 48 IDF intake manifolds, and main/air/idle jets are all accessible from the tp of the carburetor. Dellorto 48 DRLA carburetors have not been made for years; spares and jets are available from CB Performance.
$625 plus UPS.
