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..

why are you richening th elsn and then leaning the hsn, the hsn controls the entire flow so leaning it leans the lsn too, also sounds like your hsn is too lean, have you read this http://www.rcuniverse.com/forum/m_5517128/tm.htm

i got an idea.... whay dont i just set everything back to factory setting this means lsn has to be flush with the outside case and the hsn has to be .....do you know.... then ill just work from there.

but the engine makes a lot of clinging noise........
