I need some help getting back to "factory" setup on my Metro ECS controls......I feel like a NASCAR crew chief, make small adjustments and don't screw things up next time. My problem: #1) Right side pulls more than left (have to brake left to go straight) and #2) both wheels seem not to be pulling 100%. I suppose that part of the problem could be drive belt adjustment? #3) I have to really squeeze with all my might to get left wheel to lock.... Yea, I messed things up, figured I'd turn to Terry to unlock the secrets of the ECS adjustments. There are just two adjustments (wing nut & threaded rod) right?
