so I am a bit new to this quad stuff, but I just got a 2005 trail boss 330 a few months ago the owner used it a couple of times then stored it FOR YEARS so when I bought it from him gas tank fuel lines and carb were clogged with sludge from very very old gas. took me some time and alot of degreaser to clean the gas to the best of my abilities, sent the carb to get rebuilt and finally after some parts it ran. took it to apex Las Vegas last week and my friend noticed that it was leaking something of what we thought it was oil but I noticed the breather hose on top of the gas tank was bubbling and dripping so I was wondering if this is normal?
