i just baught a lt250r 1986. This thing started easy and was riding great for the first couple months. then i took it to the pit and everything was fine for the first 2 hours it ran great and had a lot of power i shut it off for 10 minutes. tried to start it and it bogged and ran with no power then stalled and wouldnt start again. The next day i took the carb off cleaned all jets and passages with carb cleaner and compressed air. i also changed the sparkplug.i tried to start it nothing i even shot either in it still nothing it does have strong spark. i then bump started it and it fired up it wont idle but has alot of power when giving it throttle. then i noticed with the air filter off a mist of gas coming through where the air filter goes. i put a compression gauge on t and it went to 150. i would appreciate it if someone could tell me where to start here im lost. and is this quad worth even trying to fix?????????
