Ist eigentlich baugleich mit Weber...wahrscheinlich aus nem Alfa oder Fiat.

Für den Weber DCOE gibt es halt eine Vielzahl von Trichtern und Venturiröhrchen...Düsen sowieso.

Hab beides auf nem 1400er gefahren..(vor 25j.)

Mit 80 mm K&N Filter und kurzen Trichtern....Rock,n roll...

Alfa had several Dellorto carburetors usually 2 carbs , for Mini use they should be calibrated on a rolling road changing and testing air and mainjets . Do not make the mistake of a to big Weber carb , normally a DCOE 40 is big enough with venturi size about 36mm : this is good for an engine delivering 100 BHp with camshafts in the region of 296 degrees ( semi race, hot rally cam )) timing of the camsahft is also crucial point , retarding a camsaft a few degrees gives better pickup lowdown rpm , advancing the camshaft is for more power in the upper rpm range 5000 rpm plus , Ignition is very important for max power ;; 36 degrees at 5000 rpm is not far off / for easy starting use less advance on the ignition , some of the old 850 distributors ar remarkably good for this purpose , I personally have been racing Mini's for some 20 years and always set up on a powerbench ( Hofmann) building my distributors by myself and checking on a distributortestmachine , ignition timing becomes important between 2000 and 6000 rpm , use an rpm limiter from Lucas that is originally in the Lotus Twincam engines and can be set by 3 small screws inside the distributor . see

Rev Limiting Rotor, Lucas

ALWAYS USE 98 benzina !! eventually ad octane booster , I have been racing with Nitromethanol ; complete different story . and use the best plugs from NGK watch the temprange for the plugs depending your driving style .
