I replaced the carb and air filter and when I started it it was racing. I seen there was another hole for one of the linkage springs so I changed it and it dropped quite a bit, but it still seems a little high unless I feather that spring that I moved. I'm sorry I don't have pics of what I am talking about, but I am short on time. Is there any way that I can adjust this to bring the speed back down to it's sweet spot? Thanks in advance!
