went to the field today and the gas engine "expert" was there, when he saw i had a gasser there he came over and looked at my plane , and asked what my needles were set at and wanted me to turn them all the way in and back them off 2 turns for the factory setting so it would run right, i am not going to tell what engine it is or what brand of propeller i have ,so all the brand loyal people wont chime in , it was turning 6400 with a 18X8 , the expert told me it thats all you will get out of it, and dont touch a thing, well to me it was running like crap and vibrating a lot ,so i started leaning the top end, ended up with 7200 and smooth running and a 1400 idle with good transition
