I want to make sure I've identified the problem correctly, so I can fix it. I rebuilt my carbs with OEM Mikuni parts, however I did _not_ replace the needle springs, since I was told the ones that come in the kits are often wrong. The fuel lines were replaced once upon a time by a BRP dealer, however, they were replaced with new tempo fuel lines, so I'm going to have to redo that again at some point. My PWC is a 98 GSX-L with the 947 motor.
The ski seems to idle fine in water, but idles high on the trailer. The real problem, however, is that the ski will bog down and die when trying to go to full throttle. If I blip the choke, then I can get past the bog and the ski seems to run fine at WOT. I do not hold onto the choke afterwards. The ski can then return to idle, and seems to idle fine again. If I want to get back up to WOT though I have to blip the choke again. The ski seems to only run right at WOT or idle, with no in-between. Clearly, based on the fact that blipping the choke fixes it means that it's running too lean. My question is what adjustments do I need to make. Based on what I've read, it seems like this could be a case of bad pop-off pressure, which means I will probably need a new needle spring. My other question is, will adjusting the high speed adjuster screw make a difference, by setting it richer? I have my high and low speed screws set to the service manual specifications.
Thank you.
