This may sound stupid, but I'm stuck at step 5 in the manual. It says "Disconnect throttle linkage by removing lock pin and unsnapping ball socket from ball on end of throttle shaft." Sounded easy enough, but how do you get the little pin out? This is one step without a picture. I see the ball on the end of the throttle linkage and there is a pin that goes through the shaft and into a U shaped bracket, but I can barely get my hand in there, let alone any kind of tool. Pliers, pin drifts, nothing like that fits in there with much room for leverage or maneuvering. Is there a trick I'm not thinking of? I don't want to just try brute force pounding or prying. Thanks.
