Somewhat new to jet ski maintenance and need some advice. I bought this ski last year .... 1995 Kawasaki 750 XI. When I bought it the hull was very clean. I rode it 2 times and noticed a little oil in the hull. I looked at it a bit and noticed one of the oil lines was cracking and leaking. I took it to the shop and asked them to convert it to premix. I guess all they did was unhook the the oil pump lines and plug the carb in lets because the oil pump is still on the crank ( no block off plate). Now the problem.... I'm slowly getting more oil in the hull. Not running oil or even enough puddle but it's just a little very spread out. A friend told me that the "plug" on the bottom of the motor may be letting the oil out and the oil isn't getting into the motor as it's burning from the compbustion. The "plug" he is referring to is the one that is connected to the little punger thing on top of the motor that you can pull to release pressure from the bottom. I really don't know what it is. Does this sound right. How do you know if it is performing properly, do I need to release this valve every once in a while? Is this problably the problem?
Thanks for the help.
