Hello everyone. Happy Easter weekend. Hope you all are enjoying the at home quarantine. It has been a few months sine my last post. Life happened, snow happened, and when either of those two things happen, I stay out of my garage. This weekend I have been doing some work on my 2003 GTI LE 717. I removed the motor, fuel tank, oil tank, cleaned the hull (since there was an oil leak from under the motor last fall), installed my new homemade oil lines, installed all new fuel lines, removed the selector switch and cleaned it and aligned the motor...basically, everything I could do even buffed the gel coat because in the next few weeks, I am sure it will be great lake weather.
However, the problem still remains. I removed the carb last weekend. Pulled it completely apart, sonic cleaned it, carb brushed every passage and used a new carb gasket kit. I did not replace the needle or seat since I replaced it on my last rebuild and this kit did not have one. I also bought a Mikuni pop off pressure tester. It was popping at 37psi. There was a slow pressure drop but very slow. So after I put the ski back together I poured some premix in the carb and it fired right up and idled well, then died. I took off the fuel filter and poured fuel in to the cup in order to prime the system. Still nothing. So I poured a little bit more fuel down the carb. It fired up and then died out. I checked the cup, fuel was still in it. So I did it once more with the return line off the tank so I could see and nothing was coming out.
Guys, do I have a bad carb? Could my pulse not be strong enough? How would I test the pulse? Put a compression gauge on it and turn the motor over? What should the psi be on the pulse. Seriously everyone, I am at a complete loss and the end of my rope with this ski. I work on cars and bikes and small engines and whatever. I have rebuilt carbs many many times so I am pretty sure I am not doing something wrong here but this is my 1st ski so who know.
PLEASE someone lead me in the right direction. These motors cannot be this complicated!
Thanks again and in advance!
