When all else fails, find someone at the local club being successful at what you want to accomplish and do what he does. LOL. Fictitious story, " Joe " has a YS 1.40 and is having issues. " John " has a YS 1.40 and it runs flawless. Joe is complaining to Pete about what a POS his YS 1.40 is and is wondering what John did to his to make it run so well. Pete observes that John is running XX fuel and XX glow plug and asked Joe why he is not using the same. Joe replies that he does not want to go out and spend the money and wants to make the engine work with what he has. Pete replies " you sell your frustration awfully cheap ".
