throttle cable issues
I know this has been discussed before but thought I might save someone a lot of headaches. I changed carbs from a holley hp with vacumn secondarys to a mighty Demon with mechanical secondarys and found I could not open the throttle all the way. The Demon required a lot more pull to fully engage the secondarys and the set up that I had would not exert enough pressure through the cable and give the desired throttle. The carb was mounted in the traditional way with the carb linkage requiring a pull from the rear of the engine. After hours of trying this and that I discovered I could reverse the carb and have the cable pull directly on the carb linkage with out a secondary set of linkage. In my case the fuel line was very easy to move to the other side. I was able to shorten my cable by 3 feet.
The end result is a throttle that is far superior in ease of operation and more linear response.
