how did you know i was running a losi lol. two of my friends are also running losi buggies and had the same carb prob this weekend. the angles of the linkages are straight it seem to be binding more like the top of the slide on the carb body than trying to rotate it. kind of like its pulling the slide down and binding but everything seems straight. it just dosent feel smooth so ill be sure to try what you said to try and fix it . thanks for the info Ron
