When i am out on the lake, i always have to pull the left lever back to go straight and follow a trail. besides being annoying it slows me down and i barely go fast enough as it is. i noticed when i had them jacked off the ground, the left side doesnt seem to turn like the right one does. It starts turning only after i pull back the right lever. Is this the way it was supposed to be? I appreciate any help and or advice.
