87 warrior-gas coming out the breather tube??...PLEASE HELP!!

hey guys hope you can help me on this one...i started her up and couldnt figure out where the leak was coming from and turned out to be the breather tube. This is the tube that is left once you take the top of the airbox. i noticed that gas was pouring out of it and i heard i might have a blown engine? is this true? what does that mean? which part is bad? Thanks for any help guys..love my warrior!!!

I dont see how that can happen. It would have to be oily gas then. Check your oil and see if the oil is runny with a gas smell. If so then you are getting gas past your piston which would be bad rings or cylinder.

Don't ride it like that, pull the carb and clean it, your float needle is sticking.

yeah something is not right here... i highly doubt there is gas coming from that crankcase breather tube?????? i mean seriously your hole gas tank would almost have to be in the bottom end, and the airbox would be completly full before it would run out the breather tube.... im lost here..... its probably a combination of bad float needle and seat and miss identification of where the gas is coming from

it is attached to the "bottom" portion of the engine - 1/2inch tube that connected to the air box top.

Did you check your oil? Take your fuel tank off and do a compression check. I find it odd that fuel would be getting to the lower part of the engine. Maybe it is back flowing from the carb into yout airbox and going down that tube. HHmm....IDK those are just my thoughts! Are you sure your floats are free?

dude, i dont know what going be going on here...... in order for gas to get in your motor like that it needs to get around the piston rings... which is entirely possible... but your talking about 2 or more gallons needed to fill up the motor and run out the breather hose.... also going the other direction... if gas ran into your airbox it would take at least 1/2 a gallon it fill it and your air filter would be completley SUBMERGED in gas and which would get sucked straight into the engine when you hit the button...

if there is gas in your bottom end you MUST MUST MUST change the oil and figure out how it go there before you run it again
