Hi Jon, I'll try to explain the situation better. It is a Walbro with adj. idle jet, idle speed is set at about 1200 rpm. Start the engine, throttle up to 3000 rpm, back the throttle down and about 2000 rpm is where the throttle stops unless you take your finger and push it against the stop screw. I disconnected the governor linkage, held my finger on the throttle keeping it closed and started the engine. I can move the throttle and it stays where I put it. It feels like it has Locktite in the bearing. Stop the engine and it free. The manifold gets very cold when it is running. In my 65 years of working on engines, I haven't seen anything like it.
