A lot of gas??. It really should not "GUSH" out. You may have inadvertently "Flooded" the engine. There are 2 way to clear the cylinders, put the plugs back in, turn the key to the on position 1st, make sure the Choke is closed, the hold the throttle all the way in and start pulling on the starter rope or use the electric starter. If it is flooded it should pop a few times and then clear the cylinders.

There is one other possibility, some Polaris models had a 10mm screw in the "Block" at the base of each Cylinder. If you back the screw out the gas built up in the cylinder will GUSH OUT. You can then put the screw back in and proceed to start the engine as earlier suggested.



You need to get to know each machine as to how it "LIKES" to start. Half Choke, Full Choke, A little Throttle, no throttle. Each machine can be different.

GOOD LUCK!

I guess the word shot out was a little emphasized, lets just say i saw vapor.
I followed the choke on, half positions... even got the book out to follow the instructions. I did a spark test.... no spark.
