I recently bought a 1995 seadoo spi. Ever since i bought it i’ve had problems where the ski would die out or wouldn’t go over quarter throttle but at time would want to go but would cut it down again. i suspected a fueling issue so i pulled the tank out and all the lines and the carb and inspected it all. i found that the internal filter in the carb was completely full of gunk and trash. just today i cleaned it with brake cleaner and compressed air and put it back in and put the carb back together as well as ran all new fuel lines and put brand new gas and oil mixture in it. when i tested the carb 2 weeks ago it was pulling about 5 in hg at the fuel line that goes to the fuel filter. now after doing all of this it is only pulling .2 in hg and its not producing enough vacuum to pull fuel through the system so it won’t start. i used a vacuum guage on the carb and with all ports blocked off and the vacuum gauge on the inlet port it held a vacuum in the carb so i know the diaphragm is good. not sure what else to do at this point
