I spent about an hour going over my linkage last night and ended up doing what Hodge said... shortened the ball link to the throttle, and cut the spring a little. The servi horn sits straight at idle (no angle), with no binding in the whole movement of the servo. Ive now only got maybe 1/4" throw for the brakes before they lock up... so we'll see.. the servo doesnt make the same 'binding' sound anymore, so hopefuly it stays in the car...
