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? |

Wait a minute, first things first. Your last comments were that you'd done it by ear, so have you found a way to set the timing yet? If not then you need to, before you do anything else. If the timing's not right then anything else you do is irrelevant.
Just an observation, there are better linkages, no question, but a lot of people have used hexbar linkages successfully for a long time. Google it and you'll find lots of hints and procedures that people have come up with to get them configured (most important) and keep them adjusted. You can make the hexbar work well. I don't want to suggest that it's not some work, or that you shouldn't spend the money if that's what you want, but I think you still have things left to do to get the thing correctly in tune first. |

I did get the timing correct. I have everything else set according to instructions. But when I have both carbs balanced at idle, at 1500 rpm on is at 7 the other is at 10. So I work on the linkage of the one lagging for a while and get it to 7 at 1500. Secure everything. Runs great sitting. Go for a drive and it gets out of balance above idle. Spent 3 hours doing this dance and never could may it work. Granted it may be operator error but I think there is something wrong with the linkage. I could try replacing parts but if it takes that long to figure it out and it needs new parts when it is only a few months old then I lean toward replacing it. But I am going to try again as you suggested before I spend the money. |
