I have an older blue head supertiger G 60 that i am trying to get running and the best I can get it to do is Start (very hard to do this) will idle very rough for about a half second then surge for about 15 seconds before it dies again, I read the manual and call myself setting up all the mixtures like it describes(they are hard to understand)!! Please help!!! All I want to do is go fly!!!! AHHHHHHH!!!!!!!
