Hey guys, I got something out of the blue and hoping a random angel-sent individual will have some sort of assistance for me. I recently installed triple Dellorto dhla 40's on my engine via an SK manifold. The engine specs as follows: stock l28 bottom end with the exception of flat top pistons. The head is a rebuilt N42 head with a mild Rebello cam. The carbs have 38mm choke, 132 mains, 33 pump jets, 7772.8 emulsion tube, 210 air correctors, and 58 Idle jets. I should note that the engine ran with SU's (SU's were replaced with triples due to leaking throttle shaft) Replaced parts: plug wires, ngk bpr6es plugs, carbs were resealed, also rechecked all bolts With that out of the way, I am having much difficulty keeping the engine idling. I have tried backing out the Idle mixture screws 3.5 turns through 6 turns, and it still won't idle. If i give it a couple pumps, it will idle only for a second. I have checked for vacuum leaks but can't find any. I can keep it alive by giving it gas, which means its somehow not rich enough at idle. The idle jets seem pretty big, so is it just a simple vacuum leak that I am somehow missing, or is it something else?

Hey all, I have triple Dellorto dhla's,but I had to switch the top cover on one due to the person I purchased them from failing to notify me of a broken float pin arm. Anyhow, I switched everything over except I can't figure out how to swap over the fuel enrichment device. I removed the nut holding on the linkage, and the cap on top as well as the spring that presses on the piston, but I can get out that piston or the arm where the linkage slides on. If anybody has any idea how to switch this over I'd greatly appreciate it. I know that they don't need to be used, but I do need to have it there on the new top cover. Thanks for any help.
