I have a .25 and .35 os fp engine and was wondering what the steps to tuning them are. I had to clean up the .35 as it was pretty gunked up. I removed both the screws and the main needle. I counted how many turns it took to get them out and put them in that many although im sure they're slightly off. I didnt count the main needle turns however. someone said to turn it 2 turns out and lean it out from there. Any help is appreciated!
