Bought our kids each one of these 170’s. Have one in the shop because it seems to have trouble accelerating. Checked plug, changed gas no change. While messing around with it, seemed to help the problem by shaking the ebrake. Looking around down there, it appears to have a restrictor on it. Is this correct? Is so can I eliminate it? If not has anyone had and fixed this issue? Thanks in advance for any guidance.
