I have a 2002 Scrambler 400. It stalled on me and then I restarted it and the idle was so high I had to shut it down. Turning the key off did'nt shut it off so I chocked it. Since then I have lubed and adjusted the cable, opened the safety throttle cover and disconnected the safety switch (so it was easier to eliminate that problem). I took the oil injection cover off and about 3 oz of rusty water came out and the cable was disconnected inside. The lever inside didn't seem to have any spring to it, so I have decided to mix my own gas. I have drained the 2 stroke oil, cut the cable to the oil injector, and have filled the tank with 40:1 gas. Is this all I need to do in order to start premixing? The throttle is still high and slow to respond. Im thinking I need to actually take the oil injector off, install a block kit, install a single cable, and then rejet it. Any answers out there? Without blocking it off is this actually creating an air leak?

 

I would definately block it off and get the single throttle cable. On the oil and gas ratio, I've heard of people using the Polaris blue at 32:1 so you may want to put some more oil in with the gas. Just to be on the safe side. (Oil is cheap). The oil injector cable may be rusted up from the water and causing it to hang up the other cable. I can't remember off hand how they are setup.? I know they reccomend you getting the single cable for this particular reason when you go with the oil block off kit.

You may have a bigger problem with the water in the oil injection sysytem. Have you noticed your coolant level dropping? If so then you may have a seal out letting water in the injection system. I've never personally heard of this. It is common for the water seal to go out and get in your counterbalancer oil.

 

did you plug the line at the intake manifold for the oil injection? If you just cut the line from the tank to the pump then air could be going through and into the engine.

Also make sure the slide is closing completely on mine a couple times now speraticly it wont close all the way and the cable has to be adjusted. I wouldn;t see the throttle cable to the oil injection causing a high idle maybe only lower. this scenario is if the oil line was still attached, there should be more fuel actually calming the idle down.
