I had a similar problem, my first step was removing the carb, and then cleaning/CAREFULLY sandpapering the grooves that are on the barrel and generally working away any tight spots. That helped a little, but it was still inconsistent. I then had a o.s speed carb laying around, so I got the neck of it milled on a lathe to the exact dimensions as my picco carb, and bam, no more tuning issues or inconsistencies with my tune... For some reason, my engine runs better too.... Then again I have a ercm modd on it, so its a killer ither way
