Nickolas,
My Da 50 never died on me but if would drop a few RPM when throttling from full to idle. A friend of mine has a DA 50 and he had his engine die numorus times and sent the engine in and had the carb line into the fuse and all kinds of stuff which didn't help. He wrapped tape around the standoffs to remove the turbulance around the carb and that seamed to slove the problem. Doing this isolated the carb diaphram and the carb air inlet. Also last fall I was doing outside loops with my Brillelli 60 and my engine pulled though just fine. When I tried doing outside loops the DA the engine faded and was going to die. I richened the low screw just slightly and it was fine after that. When I told my friend what had happened to me he tried the outside loop and his tried to die also. He richened his low needle just slightly and it went away. There seams to be a lot of experiments with the DA 50's. Some work - some don't. Lots of Luck..... Bill
