Well after much playing and changing I have to say I hate my carbs. I have done every jet size and I can't really get it to run well on anything but 70 idle jets and that is way to rich. With 60s it runs not quite as rich but the hesitation on the initial throttle is huge.
Have played with the adjustments and I think I have it running well but it never performs well. 2056 just built, 44 IDFs, 60 idle jets, 28 vents, 135 mains, F-11 emulsion tubs, 175 air correction jets. Timing at 27 to 30. SVDA Dizzy with electronic ignition. Valves recent set and rechecked. Synced at idle and 1500 rpm. Runs well at higher rev and pulls strong but I can't get rid of that hesitation. I know there will always be some but at times from a dead stop it almost stalls. What am I missing? (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) Gone through all of the Weber tech trouble shooting steps and I can't find anything that says I have something wrong. Is there an adjustment on the accelerator pump? Or do I need to up the accelerator jet? I will be going back to FI at some point but these carbs should work better than they do. Taking it to Eurohaus tomorrow maybe they will have better luck. Suggestions? |

my first suspect is still the linkage. (IMG:style_emoticons/default/agree.gif) Number one cause of dual carb issues is linkage, I've built my own linkage (much like CSP centre pull) for for over 20 years. Sync must be done with one arm off then carefully reconnected as to not change anything. Linkage must open equally through the entire rotation. Hex bars (total crap IMHO) often placing unacceptable side thrust loads on the shafts, wearing out bearings/bushings prematurely. Without a good linkage all adjustments to jets etc., are basiclly like pissing upwind in a hurricane. O2 meter is now to me a must have, if you are only doing the one car you can just borrow one, but they are so cheap now it is a wise investment. I most often "jet" with a reamer set, but of course that only works when you have to go up in size. |
