I'm running twin Dellortos and have had them set up and balanced by a respected air cooled guy. The only problem is that it won't idle smoothly and pops and splutters back through the carbs once its warmed up.
He suggested valve clearances or sticky valves but it seems strange as it appears to be happening on all cylinders. His only other suggestion was the carbs could be trash. Any thoughts before I go skinning my knuckle AGAIN checking the clearances or worse still looking for new carbs? It didn't do this before my recent head replacement but is doing it on both sides |

Sounds like timing or sticky intake valves, not carbs.
