Hi everyone! I just want to share my experience about fitting a single 40 DCOE Weber carb on a COMPLETELY STOCK A15 economy version(round port head). Baseline settings should be: Main Venturi 32; Aux. Venturi 4-5; Main Jet 140; Emulsion Tube F-11; Air Corrector Jet 200; Accel. Pump Jet 60; Accel. Pump Inlet Valve with Ex. Orifice closed; Needle Valve 200; Idle Jet 55F9. In my case, this set up increased torque, throttle response and fuel economy when compared to the factory Hitachi carb. However, if you go WOT with this set up, fuel economy goes out of the window! This set up works best with an air filter on. I used a double trumpet sock type filter from RAMAIR. If you do not use an air filter, then you should go down to 180 on the air correctors and 130 on the main jets. Hope this is helpful.


Information has been put on the non-talk page (Weber DCOE carburetor). Thanks for sharing. --ddgonzal 02:17, 12 April 2013
