back to topic, my understanding is that with EmCon carbs you can not interchage E.Tubes like in the older ones, it doesnt work that way, like the tube has a lot more and bigger holes for the transition phase, older ones doesnt have this feature, stick with the original ones and play with the fuel and the air
That may be. But, we have no baseline yet.
My Spanish 40DCOE 151s use standard jets though.
E tubes, or anything else, is not relevant if the float levels are off, jets are mismatched or incorrect.......
It's Giuseppe's giubos, not Guido's guibos, on my 78 Alfas
