Hi, I'm new to this fourm. i have a carter gocart with a 8hp tucmseh engine in it. last year while riding behind my sister i noticed that oil was spewing out of the oil dipstick hole and out of the muffler. after this we were not able to restart it. its been sitting for 1 year now and we are looking to sell it. what do you think is wrong with the motor? and how hard is it to repair it? i am strog in the mechanical field so i could modt likely repair this my self but any help or suggestions are greatly aprecheated.
