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! |

Because it is a little longer I used a Terry cable. But even thou it is longer I did have to re-route it. I circled it in yellow in the picture. Were the cable passes though the body I put a piece of hose around it to protect it.
The arms came with the CSP setup and they are made of stainless steel. Stainless steel is heavier but it just looks and feels so dam nice. As far as the engine expansion I looked at it as this way. The expansion is really small, it is more or less equal on both sides, and I tuned everything once the engine was warmed up. Having said that I haven’t noticed any major difference between cold and hot. Or at least no more then you would expect with cold carburetors warming up. I did have to add an extra spring to make the linkage snap back properly and to satisfy the Autocross rules. I’m much more happier with the CSP setup. I did fix the filter in the air cleaner cover. (IMG:style_emoticons/default/smile.gif) It was bent from previous metal cover. The spark plug wires do look closer to the arms then they are. |
