    VRO hose size

    Getting ready for ice off, and was preparing the boat (16 ft. Lowe with 70 horse Johnson). When checking the oil tank, I noticed a leak at the bulb.

    High idle

    Testing carbs?

    After receiving some sound advise ( actually made sense to me), Is there a way to bench test carbs, or a way to test if a cylinder is receiving fuel??? Carbs have been rebuilt and are on a 91 Johnson 70 hp. Thanks, Steve

    Crankshaft issue

    Due to a failed VRO2 pump number 2 cylinder overheated and scored the cylinder. The cylinder can be bored, but I am now concerned about the crankshaft. It shows a slight blueish color on the rod journals. Is this somethiung that can be corrected (ground or polished), or is the crankshaft now...
