I have been having issues with adjusting the carbs on my rebuilt 1911 so I thought I would see what a professional could do. This local mechanic specializes in Porsche's and has recently gotten a dyno so I thought I would have him adjust my Webers. The car was running fine but was rich at higher RPM's as confirmed by his dyno and sensors he was using to adjust. I had 28 mm venturis and 115 mains. It ran good but the rich situation gave me concerns particularly on a rebuilt motor. I went to pick it up after he had the car for several days and he said he was having issues. The car was running like crap, backfiring and missing. He said the carbs were adjusted good but it was either the distributor or the valves??? He had put in 195 mains and 34 mm venturis? Upon further inspection he had a 185 in one of the carbs? WTF? On top of that he charged me $320? I am done with so-called experts. This takes the cake!
BTW I am working with Jogn at AirCooled to fix! |

Hello All
Been lurking here a while and this subject caught my attention as I too am not thrilled with my crossbar set up for the Webers. Anyway, Chris, thanks for posting the photo of your setup. Have not seen that setup before and am inclined to toss my crossbar set up for this one. Just a question or two before I go and do this. Since the whole setup is located toward the back of the engine, what throttle cable do you use to reach it? Do you by any chance have a photo of where the arms connect to the carb throttle arms? Basically, what kind of throttle arm is on each of your Webers to connect all this up? Lastly, I've heard that one of the disadvantages of this type of linkage is that the throttle settings will be disturbed as the engine heats up. What has your experiance been? Have you noticed this effect at all? Hey, thanks again for posting the info and also the cable bracket .dxf file. (IMG:style_emoticons/default/biggrin.gif) Curt |
