Hi, I’m superior to raising the main nozzles for 1-2 sizes on my carburetor battery.And that’s because I just can’t adjust a reasonable relatively lean motor run with me.I’ve all had my idle mixing screws standing out on the ground position 2.5 revolutions, but unfortunately it ran a bit too thin.With more out, it reacts to the choke miserable.According to experts, you could also grease the mixture a little earlier by lifting the nozzle needles. have any of you ever been around with such alterations? Thank you very much in front, B.Struch
