Sure am hoping somebody can tell us what the problem is cuz I just picked up of these skis and both are doing the same thing full throttle at startup no throttle response one of my skis has choke so I can control the idol with putting choke almost all the way on soon as I take it off it flies through the roof the other ski has no choke so I just have to turn it right off I'm afraid it's going to score the cylinders if I try it too much please if anybody knows the answer help.
