See here is the funny part. I went to the club to fly and spent the day looking at the engine. THe tuning of the engine was the first thing we looked at. THE funny thing is that we had to change the setting to two completely different areas for vertical and horizontal flight. We got it to work with vertical positioning but once we put it on the group, it was running WAAY to rich, which caused no throttle control and eventually killing of the engine. WE took the fuel tank out twice and disassembled it to search for leaks. I found a small cut in the pressure line, which i immediately removed. THE !QUOT!clunk!QUOT! was a bit too low on the bottom of the fuel tank so we shortened the fuel line a bit. This only solved one problem in total. No more air bubbles coming in with my fuel, which anyway is a good plus because the engine was running smooth at idle and all. But at vertical, its the same crap. I got some advice form another member of the club who had the same problem with the engine. It was the same one. What he did though is after an emergency landing due to an engine failure during a loop, is he tore off the engine and pitched it out. HE told me to get an OS .46 AX. Runs great supposedly. No I'm just a 16 year old paying off the hobby by working for my dad, so a new engine is, right now, out of the question. I think i could get this to work. I took the engine apart. What i did is take off the muffler, take apart the muffler, remove the back plate, remove the glow plug, remove the whole thing on the top of the engine which is connected with 8 screws (Im sorry, I'm fairly new to this hobby, and didn't get a chance to learn about engine vocab), and after realizing i cant do much myself. Mostly due to the fact that i live in an apartment building. I cant start the engine here. I can only work on it at the club. This will suck. I really need some ideas form you guys. Oh yeah, i checked the carburetor for leeks, and its not that. There are no leaks in the carb. Its something with the engine itself. I had it on my trainer, and it worked flawlessly, i had it on my step up, the easy sport, and it worked great for the first day,yesterday, it sucked.

Please help,
