Okay so let me start with some background. I've done much research but nothing seems specific to a certain ski with that said this motor is from a '94 XP (657x). The motor has been completely rebuilt and taken from that ski and put into different ski. Ski runs great until it's in the water and won't plane out or get over what feels like 4500 RPMs though it reaches 7000 on a stand. I plan to replace the regulator today however I remember back in the day some skis had restrictors in their return lines and because this had the gray temple lines I decided to change the lines and totally forgot, threw away the old lines and now I can't look back to tell. From what I read some people say there's a restrictor between the carb and the fuel tank in the return line others say that there is a restrictor between the accelerator pump and the carb. Not sure the truth looking for somebody that has knowledge on this thanks.
