i just got a used picco off some1 on ebay, the guy was selling it because he said it was too much power for his kid. he broke it in at 11 tanks and he said it could still tak more. he was telling the truth because the piston was still shiny new with still no black marks on it, pure silver color. i fired it up and everything was fine, the problem is that it makes a very fast revving sound afer i go fast for a couple of seconds like a ringing sound. i richened the lsn and it was better but still makes the sound.....when i continue the break in process and lean out the hsn the engine chokes.... whats the problem.

does any1 have a picco 28??... can any1 with a picco tell me what their engines needle are set at e.g. lsn and hsp turn counts....

thanks in advance..
