Strong gas smell

Last time I rode my 95 sportsman 2 stroke it ran great but after parking it in the garage it has a realy strong gas smell. every time some one opens the garage door the house smells like gas. What would cause this? It has been 2 weeks and it still smells like gas. the fuel is shut off, i pulled the air filter and took it outside, and I sprayed the mud off when I got home. This quad has always had a little bit of a gas smell when it is parked but it is way worst now.

Ride it like you stole it!

The float is gotten stuck in the carb causing it to flood. Take the carb off and clean it. That should fix it. After repairing it use a fuel stablizer such as seafoam in it and ride it to allow it to mix with the gas. The carb will probably have a green build up in the carb caused by the ethanol in the gas. I use seafoam year round in my lawnmowers,atv's etc.

you must have a leak, be it so small, check all the fuel lines and look over the tank as good as you can for stains. sometimes even the fuel shutoffs don't work as they are supposed to you may look at it to make sure that it is stopping the flow to the carb. those older 2 stroke carbs. have all metal needle valve and seats and thru the years it doesn't take much for those to not seal properly.

I ran it about a week ago and shut off the fuel to run the carb dry thinking that would help but it didn't help.

are there any signs of any leaks on the floor? i assume since you removed the air filter you didnt find a puddle of gas in your airbox?

If your shutting off the fuel to the carb and running it dry then there can only be a few possible problems that I can think of. The fuel shut off valve is leaking, there is a hole in the fuel tank, or if you have a vent tube on the fuel tank the smell is coming from it.

ATV gas smell in garage

I had a very strong gas smell in my garage... I have 3 polaris'. The fix was easy, keep them filled up. Got the tip from a guy who had an explosion in his garage (reason unknown) but the fire dept said a full tank is better then a low tank. Hope this helps.
