My engine runs wide open pretty well. I think it may be slightly rich as I can see a slight fuel trail as I fly by. It is very hard to start, even with my electric starter. It doesn't like to idle and will not transition from low speed to high speed without sputtering and it usually dies. I am thinking that my low speed needs adjustment, but I don't know if it's lean or rich. Looking for some advice from you more experienced guys on how to methodically tune this engine., bearing in mind that I am a novice. Any help would be greatly appreciated.
