I just inherited a 1993 basstracker with 40hp evinrude down a cylinder. I tore the motor down to find a cyl, piston and rings scarred heavily from no oil. Ive had the block fixed got all my new parts and am putting it back together now. What im wondering is what would cause this to make sure it doent happen again. Previous owner wasnt any help just said it was down a cyl. Just from my own experience since it only affected one cyl Im thinking it was a fuel blockage in one carb or maybe reeds for that cylinder. I plan on checking the timing and doing lync and sync when its back together. Is there any thing else I should check out? Suggestion, ideas? It does have the factory vro still hooked up.
