I can probably understand jrcaster's problem. - you are fairly new to adjusting engines and not sure whether what you are doing is right or wrong. so, rather than damage it, you take the engine to the club member you feel is most knowledgeable. through whatever reason, that member is unable to tune it or keep it running, he then terms it a lemon. then another says he would like to try and has the same thing happen, then another and so on. sometimes club politics gets involved with members calling each other names or commercial issues start to get involved. somewhere along the way you start believing that the engine is faulty or it really does get damaged along the way. much later you feel it was better you did it yourself and so you end up where you started but with a lot less reliable / more difficult engine- atleast that's what happened in my case.


you guys in the US have the advantage of hobby support. we need to be self sufficient. even something as small as prop locknuts are to be custom made. and while most of you have garage workshops to do your building / testing, we don't. for example, when I built my us40, I had to try and build entire sections in a day because at the end of it, I had to store all the stuff and building board away as the same space was required for sleeping at night. the hobby is difficult for us and getting service or replacement parts expensive. that's why we have fewer chances to make mistakes and consequently the need to get help from more experienced members is more. sometimes this leads to committes or misguidance.
