I forgot to put the four wheeler in the garage when I got home and It snowed on it. Now when I start it it won't rev up. It idles fine but when u try to give it some gas, the engine knocks and it stalls out. I checked the carb and put new gas in it, any help would be great!

 

My warrior does the same thing!
all i do is pull the choke all of the way out, let it warm up, push the choke in and head for the trails.
usually if you are starting a cold engine it will take a wile to get going. If your problem still occurs after the engine is warmed up i
really don't know what the problem is.

 

The Problem still occurs after the engine is warmed up.

 

Check your parking brake adjustment. Sounds weird but it could be your problem.

 

I would check or change the spark plug and drain the float bowl
on the carb. If you had water in the fuel it will stay in the bowl
a long time .

i just had that same problem with my warrior and it was the rev limiter.
the connection to the parking brake was loose all i did was push it in and my problem stopped

Hope this helps. reply if you get it fixed.
