My triple throat Webers on Franky sneeze and cough while at mid range cruise speed. They sound fine at idle and WOT.....
Any ideas? |

QUOTE(mikez @ Oct 11 2004, 09:04 AM) My triple throat Webers on Franky sneeze and cough while at mid range cruise speed. They sound fine at idle and WOT..... Any ideas? Sure, lots of em'. (IMG:style_emoticons/default/biggrin.gif) If by mid range you mean 2500-3500 rpms, you're still on the idle circuit or transitioning to the main circuit.....a typical problem for Webers. The "cure" (assuming all else is right) is to richen the idle circuit. Then you're over rich and have other problems which you then have to cure.....which is doable. All this is pretty general cause you were pretty general with your discription....no details like ignition system, cams, jet sizes, motor size......how the carbs were tuned....float level checks, balancing (the biggest single item that is screwed up...IMO). Anyone that has a good running 9eleben motor with Webers has gone thru this or hired it done. Long distance tuning is a bitch. |
