I bought my 140 HP oil injected 2 stroke Suzuki just 2 months ago to replace a bad 120 HP Force. My old Force motor was not oil injected so I had to mix the fuel. When my old Force went bad I still had a full tank of mixed fuel in my internal gas tank. Before running this fuel through my Suzuki I asked several mechanics. They all told me the same thing. They said to run the mixed fuel through and the worst that could happen is that I would fowl the spark plugs. I did this and it ran good at times but it also smoked a lot and was bogging down a lot. I thought that this was just because there was too much oil and not enough fuel that was causing it to bog down and not run at 100%. I ran about 4 tanks and changed the spark plugs everytime I took it out. It continued to bog down and run very weak. Now the motor won't even run. When I turn it on it will just run for a second sometimes cough and then shut off. It also makes a high pitched squeek sound everytime it shuts off. Now to add to my problems, today I went to start changing fuel filters and try and figure out the problem and when I started the engine I noticed that it was peeing extremely weak and then stopped peeing altogether. So to sum it up. I have a motor that is turning over and running for a few seconds, then coughs and shuts off making a squeek sound and while running it doesn't pee. What is wrong???? I want to go fishing.
