I was riding my Polaris Scrambler 400 2002 in a Creek. I hit a submerged log and stopped dead in water up to the fuel tank. It stopped; I couldnt start it. I towed it home and found out water got sucked in the engine throught the carb. I pulled the plug and yanked on the T-Handle while water shot out of the head. I did this until clear. Now it still wont start.

I case you dont know it's a 2-stroker.

Any suggestions?

 

There's prolly more water than that in there. Check the airbox and filter for water and clean and flush the whole carb. Change the oil too.

 

Thanx; Ill try that. I didnt get a manual. ANy body know where the oil plug is? Or how I can get a cd manual?

 

Ohh, it's a 2 stroker...it prolly doesn't have an oil prug then.

 

Pull off the head pipe. take out the plug, put your thumb/finger over the plug hole and rip her over a bit. That forces the water out through the exhaust manifold and does a much better job overall.

As for oil plugs, didn't think there would be one on a 2-stroke engine?? Dunno much about that though .. they just get their lube through the fuel system as I understand it.

Does your machine use oil injection or pre-mixed fuel?

 

My 2 stroker Scrammy uses oil injection. It still wont start either. Sucks.

 

Fuel, Compression and Ignition are required for any internal combustion engine to start/run.

Make sure your carb does not have any water in it and it supplies fuel properly.
Do a spark testing - you want to see a nice fat blue spark jumping between the plug electorde and ground frame/engine when cranking.
Do a compression check - I would it should be around 150~180 psi, check your manual.
If your engine speed was high when the engine sucked in water, there is a chance of cylinder hydrolocking bending the con-rod and/or twisting the crank - the worst case scenario. Hope that's not the case though.

 

scrambler 400's although 2 stroke do have a small oil tank for the tranny. i dont know were to drain it but im guessing on the bottom of the eninge toward the tranny. look for a hole in ur skid. and u can check the oil by taking off ur seat and looking between the carb and the gas tank and ull see wut looks like a over size screw. thats were u check it
