Just had an issue with one of my DL's today this engine is about 2 years old now, fired the engine up and went to tune it and it ran very good then all of a sudden it stopped i fired it back up and the engine would not run over half throttle, it would die out after passing the half way mark, I tried to tune it i richened up the high end and that would not do it so now i have pulled the engine off and will see if the high end needle is cloged and clean the carb. I also checked the spark plug after removing the engine and it looked good but i will change it anyway. I will let everyone know what i find as i go along. I also thought about calling bob to get another sensor. I have herd about these things going out and only running at lower RMP.

Anyone with any ideas?
