I just purchase used Suzuki LT 125 quad 1985. When I tried to start it gas was pouring from carburetor. Had to clean this thing, it had some clear sticky coating in it. After some good cleaning it start to work. Engine runs strong and do not burn oil and it does not smoke. From what I can see it was not running for about 2 years. It has 1000 miles on it. Now question is: what to do with oil. Just change to new one or add something to clean motor up? Thank you
