Worked on determining why the throttle sticks. Removed the throttle cable. Checked move movement of the throttle with the cable straight. Still sticks. Not because of any bend in the cable. Removed the Aero Injector. Remove the bolts holding it together. Worked the cable to see why it is sticking. Nothing obvious. Removed the needle. Polished the needle. Installed the needle. The slide now moves freely. Put the Aero Injector back together. Installed the Aero Injector back on the engine. Installed the mixture and throttle cables. It now appears that the throttle moves smoothly.
