So I replaced the carb on my 22hp Ariens riding mower. Briggs and Stratton engine. Took old carb off put new one on. Put throttle and choke linkage rods back on like before. So I thought. My problem resides with the throttle linkage. So when I start the mower, it runs at full throttle. I couldn't figure what was wrong at first then after looking, I noticed the throttle was basically wide open with the rod being pulled down by the throttle arm and spring it attaches to. It's almost like it's backwards which I know it shouldn't be. Any thoughts on why that spring arm for the throttle would be wide open as it pulls down on the throttle lever of the carb?
