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! |

Years ago there was a discussion about carb linkage and four cylinders, and I seem to remember that someone had a problem with the center mounted bell crank linkage and thermal expansion of the engine. Is this just BS?

Is this just BS? You just need a hair of slack in your cable for expansion. Most likely there was an installation/set-up issue Think about it...as it expands the linkage would equally adjust with the expansion, as long as it has slight slack on the wire (at idle). |
