I have the 2554 with Kohler 730 engine 25HP twin cylinder. I am recovering from surgery and I knew I had a carb problem, so instead of trying to clean the old one out, I just ordered a new one. My issue is this - I asked my son to take the old carb off and I'd walk him through putting it back on. Big mistake! Since I wasn't there to see it come off, I am confused as to how the linkages attach and work. I have the diagram, and I have the throttle linkage attached to the governor. I have the choke rod attached to the choke linkage. When I manipulate the throttle, a bracket swings back and forth but the throttle barley moves at all. It's not running right now. I have everything attached as the diagram says to, but I just don't see how I'll have any throttle at all doing it this way. Any help?
